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. SOme of this work has prompted industrial sponsorship in the area of photostability problems. Our most recent study involves biological chromophores.
