Abstract

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.
