interests focus primarily on the application of laser spectroscopic methods
to problems in atmospheric chemistry, chemical vapor deposition, catalysis,
and combustion chemistry. One of our ongoing fundamental projects
utilizes an in-house tunable infrared diode laser spectrometer to study
gas molecules cooled to very low temperatures in a molecular beam.
Emphasis areas for these fundamental studies include organometallic compounds
that are important either because of their known catalytic potential or
are utilized as precursors for the generation of thin metallic films.
Other projects currently being pursued in the group include several trace
gas analysis projects. Here, a high resolution infrared diode laser
spectrometer is interfaced with a 200 m Herriott cell to identify and quantify
gas phase molecules present at sub-ppb levels. In one case we are
attempting to identify and quantify certain biomarkers in environmental
tobacco smoke. In another set of experiments, we are examining the
infrared signatures in soil gas emission samples in an effort to identify
the dominate biogeochemical processes in agricultural soils during crop
production. Some recent publications include:
