Lifetime and quenching measurements of C2H emission produced by vacuum ultraviolet photolysis of C2H2
Abstract
The state of the art tunable VUV sources are used to produce excited C2H photofragments (C2H*) via the photolysis of acetylene molecules. The quenching rate constants of the C2H emission by a number of species are determined. The collision free fluorescence lifetimes are measured at different excitation wavelengths. The excitation energy threshold for producing the observed emission is determined. In addition, a correlation between the excitation energy and the emission wavelength is observed.
