The focus of my research is the application of quantum mechanical, molecular orbital methods to the determination of molecular structure, fundamental vibrations, and other molecular properties. Projects include the determination of transition state structures and frequencies for reactions thought to be important in atmospheric chemistry. The results of these calculations are then used, in conjunction with transition state theory, to determine rate constants for the reactions.

Other projects include:

1. The study of unusual bonding features in species such as ONF₃, OCF₃^- and FNO_2.

2. The stability of H₂O₃ and related isoelectronic molecules.

3. The energetics and mechanism of the reaction:

HLi + (LiNH₂)_x = (LiNH₂)_x-1Li₂NH + H₂

and related reactions.
