World of Chemistry Science and technology greatly contribute to our happy and long lives. The goal of this course is to learn how chemistry impacts our daily lives in common and extraordinary ways. After learning basic concepts of elements, atoms, and molecules, we will explore topics in energy (nuclear, solar, batteries, fuel cells, fossil fuels, and metabolism), environmental issues (acid rain, global warming, and ozone depletion), health (food and drug), synthetic material, and art (color, forgery detection, and art restoration).

Foundations of Chemistry CHEM 0102 is the foundational course required for all students beginning chemistry. In this course, we will introduce the essential vocabulary and symbolism used to describe matter, the chemical theories that relate microscopic structure and composition to macroscale physical properties, and the mathematical use of measurements and chemical equations to relate products and reactants (i.e., stoichiometry) in pure substances and solutions. We will use short lectures and small group work to solve problems collaboratively. During discussions, we will show demonstrations and apply theory to analyze observations. Students should visit go/chemplacement to determine if they are eligible to enroll directly into CHEM 0105.

General Chemistry I Major topics will include atomic theory and atomic structure; chemical bonding; stoichiometry; introduction to chemical thermodynamics. States of matter; solutions and nuclear chemistry. Laboratory work deals with testing of theories by various quantitative methods. Students with strong secondary school preparation are encouraged to consult the department chair for permission to elect CHEM 0104 or CHEM 0107 in place of this course. CHEM 0103 is also an appropriate course for a student with little or no prior preparation in chemistry who would like to learn about basic chemical principles while fulfilling the SCI or DED distribution requirement. Students with AP Chemistry scores of 4 or 5 OR Chemistry Placement scores of 21 or higher are NOT allowed to enroll in CHEM 103. Students MUST have taken the Chemistry placement exam and earned a score of 20 or less.

General Chemistry II In this course, we will cover introductory chemistry topics including chemical kinetics, chemical equilibrium, acid-base equilibria, chemical thermodynamics, and electrochemistry. Lab work includes inorganic synthesis, qualitative analysis, and quantitative analysis in kinetics, acid-base and redox chemistry. Students may only enroll in this course if they have previously taken and passed CHEM 0103. This course will be offered for the last time in Spring 2026.

General Chemistry In this course we will introduce students to the fundamental theories and concepts in chemistry.

Whether it is calcium in cell signaling and muscle contraction or iron for the transport and storage of O2 molecules in the blood, metals are engraved in bioorganic systems in different states and concentrations. In this course, we will first familiarize ourselves with the basics of inorganic chemistry needed for understanding bioinorganic chemistry. We will learn the nature of chemical bonding in bioinorganic systems with the theories and examples associated with them. We will then move toward the biochemistry of molecules - the building blocks of proteins: amino acids, followed by processes of RNA, DNA, and protein synthesis. We will conclude the course with a broad discussion on the role of metals in biological systems and their applications with possibly a few specific examples in detail.

Foundations of Inorganic Chemistry This course will expand on general chemistry topics (atomic structure, periodic trends, and bonding theory) to survey inorganic chemistry. This course introduces students to new topics such as solid-state materials chemistry and coordination chemistry and applies these topics in areas such as acid-base and redox chemistry. The relevance of this content to energy technologies, medicine, environmental chemistry, and industrial processes will be discussed.

Chemistry of Energy Conversion With global energy use on the rise, it is essential to understand the different energy systems that are currently in place and how they can, or in many cases, cannot meet the world’s future energy demands in a sustainable manner. In this course we will begin with a brief overview on the energy sources themselves: potential energy (hydro), kinetic energy (wind, tidal), thermal energy (geothermal, ocean thermal), radiant energy (solar), chemical energy (oil, coal, gas, biomass), and nuclear energy (uranium, thorium). Once we understand the energy sources, we will apply the tools of inorganic chemistry (simple bonding, symmetry, transition metal chemistry, ligand field theory, and thermodynamics) to explore the larger topic of energy conversion. We will examine how chemistry provides an incredible opportunity when it comes to understanding energy conversion by approaching the problem from the atomic level all the way up to the empirical macroscopic world. Although the path to sustainable energy will be examined primarily through the lens of chemistry, our learning will be placed in the context of political, social economic and environmental goals, which strongly influence future energy production.

Environmental Chemistry & Health IIn this course we will investigate the relationship between molecular structure and the behavior of chemical pollutants in natural and built environments, the science underlying health effects of toxic exposures, and environmental justice concerns associated with pollutant exposures. Through readings and active problem solving, we will examine the chemistry governing global transport and partitioning of chemicals among soils/sediments, waters, the atmosphere, and biota (including humans), as well as contaminant remediation strategies. We will study foundational principles of environmental toxicology and take a case study approach to identifying patterns of environmental injustice. In the laboratory, we will apply methods for monitoring pollution, understanding pollutant behavior, and assessing toxicity.

Medicinal Chemistry Medicinal chemistry combines organic chemistry with biochemistry, analytical chemistry, physical chemistry, molecular biology, pharmacology, and medicine. As chemists we try to correlate the molecular structure of pharmaceutical treatments (i.e., "drugs") with their biological activity to understand disease and to develop both new and improved treatments. In this course we will survey the major categories of diseases, drug targets, and drugs using a case-study approach. In addition to mid-term exams and a shorter group presentation on a disease category, the course will culminate with group-based final projects (presentation and written paper) about the design, development, and proposed future directions of treatments targeting a specific disease.

Chemical Biology In this course we will explore scientific advances propelled by research at the interface of organic chemistry and molecular biology. The field of chemical biology involves the manipulation of biological macromolecules (proteins, nucleic acids, lipids, and carbohydrates) using synthetic organic chemistry. These organic transformations are not used by nature and thus permit site-specific modifications that enable study or alteration of macromolecule function. Examples include antibody-drug conjugates for targeted chemotherapy and fluorescent probes of macromolecule interactions. In the lab, we will apply the techniques of chemical biology and ask new research questions. Fundamentals of molecular biology will be discussed as they pertain to our exploration of chemical biology. (CHEM 0205) (5 hrs lect., 5 hrs lab).

Students will learn inert atmosphere synthetic techniques and how to use a glove box.  The synthesized Mo-Mo complex will be characterized by UV-Vis, IR, 1H and 31P NMR spectroscopies, and cyclic voltammetry.  In the second half of the semester students will conduct two physical chemistry experiments.  First students will carry out a kinetic study of the  isomerization of the  Mo-Mo (alpha to beta or beta to alpha) complex by UV-Vis spectroscopy.  Finally, students will obtain the high-resolution IR spectra of acetylene and deuterated acetylene and analyze the rotation-vibration spectra using statistical and quantum mechanics to obtain structural data and interpret the peak intensities.  In addition to the laboratory activities, there will be lectures on metal quadruple bonds, principles of UV-Vis , IR, 1H and 31P NMR spectroscopies, cyclic voltammetry, and statistical mechanics.

Professor Guiberson was a very passionate and energetic professor that cared about her students. However, lectures would often be describred in a confusing manner which is hard to understand topics in class because the textbook can also be dense. Weekly practice problems were helpful but again hard to understand without a solid grasp on concepts. Weekly quizzes were quite easy which stands in contrast with the exams. Professor provides almost no practice for exams and found it extremely hard to prepare for exams. Overall course content was interesting but everything builds on each other. I found lab and lab professors to be more considerably more helpful in really understanding concepts. 

I was surprisingly disappointed with this class. I had Professor Vasiliou for Gen Chem and she was great, but she just didn't seem motivated to teach this class. She rarely answered a question directly, and had a tendency to go on long tangents about broad issues only distantly related to the material. I just wish we had covered more actual content of thermodynamics and kinetics in class to prepare us for the exams.

I didn't find that AJ was always the best at explaining topics, but she was very kind and knowledgable about the material. You just really have to push to get answers to your questions. But I found the exams quite easy, and so was the grading! Not a course to worry about.
