QUANTITATIVE STUDIES BY OPTICAL SPECTROSCOPY OF ENERGY EXCHANGE MECHANISMS IN SIMPLE GASES AND SOLIDS

Abstract

Emission studies have continued in fast flow systems of nitrogen energized in a microwave discharge. By changing parameters of pressure, temperature, and mixture, silicon tetrahalides added after the discharge have produced two electronic systems of SiN, and two separate, unidentified emitters in the green and in the orange spectral regions. Addition of CO2, N2O and CO has shown near infra-red emission of these molecules, caused by transfer of vibrational energy from the ground electronic state of molecular nitrogen. To further the understanding of the N2(+) emission observed in some afterglows, a detailed perturbation calculation for the v = 1 level of the B square sigma & state and the v = 11 level of the A square pi has been undertaken. A new set of studies in a well-behaved plasma produced by means of a brush cathode was undertaken. Spectroscopic, electron probe, and voltage-current measurements are being made in hydrogen and in hydrogen-helium mixtures at pressures near 1 mm Hg. The condensed phase studies of molecular solids has not had any significant results.
