Time and State Resolved Studies of Molecular Decomposition.

Abstract

The combination of laser excitation of overtone vibrations with time resolved spectroscopic detection of reaction products provides uniquely detailed data on the rates and disposal of energy into products in unimolecular decompositions. The decomposition of a cyclic peroxide, tetramethyldioxetane, is the first example of a vibrational overtone initiated reaction studied in a free jet expansion, where the thermal energy content of the reacting molecules is small. Low pressure gas phase data on hydrogen peroxide reveal the partitioning of the excess energy of the reaction in the OH products and provide new data on the vibrational overtone spectroscopy of this molecule. A new molecular beam apparatus has been constructed for extending these studies to a wider range of molecules using additional detection techniques.
