 Abstract
Rayleigh scattering and laser induced predissociative fluorescence are employed for capturing two-dimensional images of temperature and species concentration in a laminar nonpremixed flame of a diluted hydrogen jet. Rayleigh scattering cross-sections are experimentally obtained ar 248nm. Dispersed LIPF spectra of OH and O are also measured in a flame in order to confirm the excitation of single vibronic state of OH and O .OH and O are excited on the P(8) line of the A band and R(17) line of the Schumann-Runge band B , respectively. Fluorescence spectra of OH and Hot O are captured and two-dimensional images of the hydrogen flame field are successfully visualized.
