Rotational-Vibrational Level Relaxation Effects on Laser-Induced Fluorescence Number Density Measurements of Hydroxide in a Combustion Environment. II. Effects on Vibrational Level Populations.
Abstract
A full vibrational-rotational level rate equation model has been used to investigate the application of laser-induced fluorescence techniques to number density measurements of hydroxide in a combustion environment. The extent of deviation of the population in the laser-pumped vibrational level from the two-level model prediction, due to collisional exchange mechanisms, was investigated for a range of pressures, temperatures, laser powers, and collisional exchange rates. For accurate number density measurement using wide bandwidth detection, it was determined that lower laser intensities are required at all pressures. (Author)
