RESEARCH ON NEW TECHNIQUES IN ABSORPTION AND EMISSION SPECTROSCOPY.

Abstract

A laser has been used to stimulate IR emission from organic compounds. Using a simple experimental system, it has been found possible to detect about 20 micrograms of gaseous organic material. Using a laser beam of wavelength 10.6 microns, IR emission at wavelengths as low as 3.3 microns were observed. This would require 4 photon collision on conventional theory. The mechanism of excitation is not clearly understood. Emission spectra in the ultra violet have been observed when organic compounds are put into an Rf plasma. Emission characteristics of C-P, C-O, C-halogen and S-H bands were observed. (Author)
