Nonlinear Optical Spectroscopy of Molecular Complexes.
Abstract
A Coherent Raman Loss Spectrometer was set up and used to obtain spectra of static and jet samples of CO2 at 0.003 wavenumber resolution. Coherent Raman methods were used to examine small hydrogen bonded clusters of HCN in static samples and in jet expansions. The first Raman data for a hydrogen bonded complex formed in jets was obtained, and preliminary studies of water and hydrochloric acid jet expansions have been done. CARS spectra of van der Waals complexes were taken. In the carbondioxide dimer case the most stable conformation was found to be an offset parallel shape rather than the polar T form suggested by others previously. The first CARS detection of a low freqency intramolecular librational mode was made of the CO2 dimer. The energy distributions of nitrous oxides and carbon trifluoride photofragments of carbon fluoronitroxide were studied using CARS as a probe technique. This was the first detection of CF3 radical by Raman methods. The photodissociation of this molecule in low temperature argon matrices was also studied.
