Welcome

Our group works in the area of cluster science whose broad aim is to understand how the properties of individual molecules evolve into those of macroscopic samples.  We perform high resolution spectroscopic studies of small molecular clusters, from which we elicit extraordinary detail about molecular and electronic structure.

Microwave spectroscopy in a supersonic jet has been used to establish that sulfur trioxide reacts with carboxylic acids to form carboxylic sulfuric anhydrides, RCOOSO2OH. These anhydrides represent a relatively new feature of the chemistry of sulfur oxyacids and may have implications in atmospheric chemistry.

DAPPERS stands for Data Analysis Package for Productive and Enthusiastic Rotational Spectroscopists. DAPPERS is designed to be an all-in-one tool for rotational spectroscopy that simplifies and expedites the processing and fitting of microwave spectra. The program features a graphical peak finder, a sophisticated fit searching algorithm based on spectral progressions, and the ability to quickly and easily run Pickett’s SPCAT and SPFIT programs. Additionally, DAPPERS is organized in a user-friendly format with informative help menus designed to instruct the user how to properly operate every component of the program.
