Abstracts:

For an improved understanding of combustion it is important to have information about concentration distribution of various radicals. Laser-induced fluorescence of OH radicals has been widely used in combustion research for the determination of concentration, flame structures or temperature. A propane-air laminar premixed flame at atmospheric pressure was object of investigation. Experimental measurement of excitation spectrum OH radicals was carried out in spectral range 283-284 nm in increments of 5 pm. The excitation spectrum of OH radicals was compared with excitation spectrum which has been calculated using the LifBase software. OH radicals was excited in the υ''=0 → υ'=1 band of the A-X electronic system at wavelength 283.55 nm and spectrally resolved detected in the (0,0) and (1,1) vibrational bands around 305 - 320 nm.
