Research Interest:

Recent research activities have focused on the high-resolution spectroscopy of small gas phase molecules, with particular emphasis on metal-containing radicals, such as AuO, PtF, NiH. Our experiments are based on intracavity laser absorption spectroscopy, performed in collaboration with Prof. James J. O'Brien at the University of Missouri - St. Louis. We have special interest in recording rotationally-resolved molecular electronic transitions, which can provide many fundamental molecular constants for diatomic metal-hydride, metal-oxide and metal-nitride molecules. The significance of the research is based on the interpretation of the obtained molecular constants, especially as they relate to chemical bonding and molecular reactivities.

Teaching Interest:

My teaching assignments usually include Physical Chemistry (Chem 361a/b), Physical Chemistry Laboratory (Chem 365a/b), and Advanced Physical Chemistry (Chem 561). Course materials can generally be found on SIUE's Blackboard webpages.
