Physical Chemistry

   Professor Collins' main research interests are in the area of low-temperature (10K) spectroscopy. The technique of matrix isolation currently is being used to study hydrogen-bonding of water complexes to molecules of biological interest with Fourier-Transform Infrared (FTIR) and Fluorescence Spectroscopy. The ultimate goal is to be able to study hydrogen-bonded complexes at 10K in order to elucidate the number of molecules that are in the complex by correlating FTIR structural studies with the excited state potential energy surfaces as indicated by luminescence data.
