COMBUSTION GAS EMITTED RADIATION AND CHEMILUMINESCENCE PHENOMENA.

Abstract

The study was concerned with spectra of premix flames and combustion gases at low pressure, with applications to chemiluminescence, kinetic and reaction mechanism elucidation. Oxidizers were O2, NO, N2O, ClO3F; fuels were CH4, C2H4, C2H2 and H2S. Spectral scans coupled with thermochemical analyses indicated several bimolecular reaction mechanisms forming excited species at low pressure with characteristic signatures: CH + N to CN* + H; N + O to NO (doublet-pi) to NO*; CH + CH to C2* + H2; C + HO2 to CO* + OH; CH + SH to CS* + H2; CCl + OH to CO* + HCl; C2 + ClO to CCl* + CO. Several previously unreported CO bands (4th positive system) with v' = 0,1,2, and 3 were observed. In addition, emission from NH, OH, SO, S2, CH and CH(+) were seen. (Author)
