Summary

 

Summary

Our work involves development of the metholodgy of quantum chemistry and computational studies of photochemical reactivity.

Method development work involves the development of electronic structure methods and ab intio molecular dynamics. We are a developer of the Gaussian program for electronic structure computations.

Applications to photochemical reactivity are focused on problems involving at least two potential surfaces, known as non-adiabatic chemistry, including photochemistry and electron transfer. This work has been directed at many important areas of experimental development. Examples include classical mechanistic organic photochemistry, photoinduced electron transfer, inorganic femtochemistry, energy transfer mechanisms in bichromophoric systems, photochemical stability, intramolecular quenching, photochromic systems, polymer photophysics, and biological femtochemistry. 

Recent work has been focussed on problems where electronic and nuclear dynamics can be asynchronous.  An example is charge migration. Here laser excitation may excite many states and one can observe fast electron dynamics.

We have recently collected some of this work in a book (Theoretical Chemistry for Electronic Excited States) published by the RSC. (http://dx.doi.org/10.1039/9781788013642).  Some additional background material can be found at http://www.rsc.org/campaigns/m/lc/lc17021/physical-chemistry/#robb
