Physical Chemistry

Molecular structure, X-ray diffraction, magnetic resonance Preparation and characterization of novel inorganic complexes One project involves the preparation and characterization of novel complexes of metal ions such as Cu(II) and Ni(II) with multidentate ligands containing thiolate, disulfide and imidazole ligands. Recently, we reported the preparation and characterization of an unusual trinickel species that contained nickel(II), nickel(I) and I(I) [iodonium] in a single cation. Currently, we are examining a complex system that contains isomers that differ only in the length of two bonds. Self-coordinating metalloporphyrin as models of bacteriochlorophyll A second project deals with the preparation and characterization of self -coordinating metalloporphyrin and related dimers that serve as useful models for the special pairs of overlapping bacteriochlorophyll molecules present in bacterial photosystems. Our goal is to understand how the relative orientation of these molecules gives rise to the unique spectral properties of these systems. Three different porphyrin and bacteriochlorin dimers have been studied extensively to date. Both projects are conducted in collaboration with professors Schugar and Knapp of this department Chemical education: Undergraduate chemistry for nonscientists A third interest is chemical education. With the help of NSF funding, we have designed a novel undergraduate course intended for nonscientists. The goal of "Impact of Chemistry" is to help create an informed citizenry capable of appreciating science and of critically analyzing complex issues involving science. Written assignments (essays), classroom participation (public speaking) and group work (teamwork) are integral to the course, along with the expected problem solving, experimentation and introduction to the methodology and content of chemistry. The course contains two-week modules in which chemical principles are intertwined with social/politica1/environmental/ethical issues. Most modules contain a case study in which students present and defend a given position related to a topic of current interest. A class project involving the analysis of household dust by X-ray fluorescence out the curriculum.
