Laser probes of natural gas ignition chemistry. Annual report, January-December 1985
Technical Report

OSTI ID:5715085
The research described is aimed at developing laser-induced fluorescence of various hydrocarbon species for use as probes in natural gas combustion chemistry, and developing an understanding of the mechanism of formation of chemiluminescence of certain radicals found in natural gas combustion. The collisional quenching of electronically excited OH and CH molecules was measured at elevated temperatures, and a theoretical approach of OH quenching due to attractive intermolecular forces was used to estimate quenching rates in a variety of flames. A computer model of the pertinent chemistry of radical emission was formulated and compared with measurements in a laser pyrolysis system.
