Stuart Hall - Rector Complex Room 1107
For years, the Samet research group has been using the "matrix isolation" technique - the freezing of molecules in an inert gas at close to absolute zero - to study hydrogen bonding. Specifically, nonconventional hydrogen bond linkages such as C-H---N, C-H---O, and C-H---pi have been the focus of published work. Recently, the team pioneered a new technique called Polymer Soft Landing Isolation, which is a twist on the standard matrix isolation technique. In particular, molecules are now deposited onto a polymer surface, rather than a clean surface, so that hydrogen bonding throughout the polymer may be studied. This new technique, which is unique to Samet's laboratory at Dickinson, allows for the probing of the self-assembly process and the building of nanostructures, which has brought her traditional matrix isolation research into the realm of nanotechnology. Outside of the research laboratory, she studies the chemistry of certain illnesses that the conventional medical system struggles with, such as vitamin B12 deficiency, gluten-related problems, and thyroid disease. At the advanced level, she teaches in the area of physical chemistry that involves quantum mechanics and spectroscopy, and also inorganic chemistry. Her scholarly pursuits in the field of chemical education include studying the role of chemistry in history, and incorporating both nanotechnology and lasers into the undergraduate curriculum.
CHEM 341 Quantum Chem & Spectroscopy
Examines how the Quantum Theory, and in particular the Schrödinger Equation, makes possible the determination of translational, rotational, and vibrational energies of molecules, and how spectroscopy experimentally determines the energy and hence structure of atoms and molecules. Three hours classroom per week. Prerequisites: 132 or 141, MATH 171 and PHYS 141 or 131, or permission of the instructor. NOTE: PHYS 141 or 131 may be taken concurrently with CHEM 341.
CHEM 347 Concepts of Inorganic Chem
This course will cover fundamental concepts in inorganic chemistry to include: periodic trends, atomic and molecular structure, ionic bonding and crystal structures, solubility of ionic solids, acid-base chemistry, structure and bonding in coordination compounds, and reactions of transition metal complexes. Throughout the course the unifying theme will be the application of principles of structure and bonding to predict and explain reactions involving inorganic compounds. Three hours classroom and four hours of laboratory per week. Prerequisites: 244, 341 or concurrent enrollment.
