Role of Electron and Charge Transfer in Chemical Reactivity.

Electron and Charge transfer are closely related concepts which have been shown to play a distinctive role in determining the nature of chemical reactivity. Breakthroughs in this area have been made by the group of Jay Kochi in studying inorganic, organic, and organometallic reactivity. The FERET (free energy relationship for electron transfer) equation developed by Kochi is a unifying equation which describes the relationship between optical and thermal electron/charge transfer. This approach is in the great tradition of developing conceptual understanding of chemical reactivity based on connecting fundamental experimental properties with theory, such as the establishment of the electronegativity scale through the study of bond energies (Pauling).

Our research is concerned to uncover new aspects of this exciting new area. We are utilizing several experimental and theoretical methodologies in our research, to examine the role of charge transfer in reactions of biological interest.

1. Simulation and analysis of reaction mechanisms in electroanalytical chemistry, mostly cyclic voltammetric and double potential step experiments. (BAS 100A)

2. Electron Paramagnetic Resonance. (Resonance Instruments X-band ESR Spectrometer).

3. Development of semi-quantitative computer relational database model approaches to understanding charge transfer.

 

Education (The Workshop Project)

I am interested in promoting the reinvention of science education to bring it in line with the traditions that make science exciting and alive. That is, learning science is not a passive activity, but is an activity in which one is engaged in with ones peers in a vibrant discussion and debate of fundamental principles and applications. As director of the NSF - DUE funded "Workshop Chemistry Project" I am interested in facilitating adoption and implementation of the "Workshop Model", a peer-led team learning model for teaching and learning chemistry and other science disciplines. For a more complete description of the Workshop Project, please consult the Workshop Project Web Page.
