ENERGY TRANSFER FROM HIGHLY EXCITED SPECIES.

Abstract

The research discussed has used both discharge techniques and photodecomposition to produce electronically excited species. Particular attention has been paid to excited species in metastable states. Emission spectroscopy has been used to determine the species produced, using both image-tube spectrographs and filter-photomultiplier combinations. Relative rate coefficients for energy transfer have been determined by monitoring the intensity of the metastable emission as a function of added gas. Recently, absolute rate coefficients have been determined using a pulsed photolysis-signal integration system. The studies have concentrated on the energy transfer reactions of O(singlet D), O(singlet S), O2(b singlet Sigma g (+)), N(doublet D), N2(A triplet Sigma u (+)), and N2(B triplet Pi g). Some of these have important atmospheric applications. (Author)
