Excited-State Energetics and Dynamics of Large Molecules, Complexes and Clusters.

Abstract

New techniques for spectroscopy in supersonic expansions and in the development of specific supersonic sources were developed. Vacuum Ultraviolet Absorption Spectroscopy in Supersonic Expansions. We have combined the techniques of vacuum ultraviolet (VUV) spectroscopy together with planar supersonic jets, which allows for the interrogation of absorption spectra of large molecules cooled in supersonic expansions in the near VUV region. Development of Conical Nozzles for Supersonic Jets. Conical nozzles (nozzle opening angle theta = 30, and nozzle diameter D = 0.3 mm) were constructed and used in conjunction with a magnetic pulsed valve. The use of conical nozzles considerably enhances clustering in supersonic expansions, facilitating studies of large van der Waals complexes and clusters.
