Title:High-resolution spectroscopic studies of reaction intermediates relevant to atmospheric chemistry
Author(s):Endo, Yasuki
Abstract:We have been studying short lived reaction intermediates and complexes containing short lived species by high-resolution spectroscopic means. Laser induced fluorescence spectrosocpy with resolutions up to 0.02 \wn is used for observations of electronic transitions, and Fourier-transform microwave (FTMW) spectroscopy and FTMW-mm-wave double resonance spectroscopy are used for observations of pure rotational spectra. Both of the methods are combined with supersonic jet sytems equipped with pulse discharge nozzles to produce short lived species. Last several years, we are concentrating on observations of short lived oxygen bearing species and their complexes especially with water. Such species are considred to be important in atmospheric chemistry, since chemistry in the earth's atmosphere mainly proceeds as oxidation reactions of trace species existing in the atmosphere, where various oxygen bearing reaction intermediates are playing important roles. Detections by high-resolution spectroscopy are expected to provide valuable information on these species. Furthermore, importance of molecular complexes containing reaction intermediates with water in atmospheric chemistry has been discussed recently, where detections of such species are highly required since quite limited experimental information has been obtained so far. In the talk, results of a number of such species, either monomers or complexes, studied recently in our laboratory will be reviewed.
