PHOTOCHEMISTRY OF AZO COMPOUND AND STUDIES IN UNIMOLECULAR REACTIONS.
Abstract
PHOTOCHEMICAL PRODUCTION OF 'HOT' MOLECULES: Pressure dependence investigation during photolysis of 2,3-diazabicyclo (2,2,1)-2-heptene (DBH) showed that although the incident radiation may be monochromatic, the mechanism of dissociation is such as to result in energy dispersion with the result that the vibrationally hot molecules produced are by no means monoenergetic. PRIMARY PROCESSES IN THE PHOTOCHEMISTRY OF CYCLIC AZO COMPOUNDS: Fluorescence emission was observed in both DBH and 2,3-diazabicyclo (2,2,2)-2-octene (DBO). The gas-phase spectra for DBH showed that the excitation spectrum closely parallels the absorption spectrum and that emission spectrum is a good qualitative mirror of the latter. DBO spectra were similar to those of DBH but the clear mirror image relationship observed for DBH was lost. ENERGY TRANSFER: Various substances, including CO2 are being studied in regarding their efficiency as energy transfer agents in the gas phase photolysis of DBH into vibrationally excited compounds.
