Molecular Collision Processes in Cases and at Surfaces

Abstract

Our research centers on the use of Fourier Transform Infrared Spectrometry (FTIS) to determine the distribution of rotational and vibrational energies in molecules. Our particular concern is with the effects of gas-gas and gas-surface collisions on these internal states. By studying the changes in energy and structure that occur during such collisions we aim to elucidate the kinetics and dynamics of the reactive and inelastic scattering events that play leading roles in many important processes of both technological and scientific interest. The collision processes under study are brought about with the aid of supersonic free jets expanding into vacuum from small sonic orifices or nozzles.
