Abstract
Results of photodecomposition studies of liquid cyclohexane n-octane, n-decane and methylcyclohexane with 7.6 eV photons are reported for various temperatures. In all cases the yield of molecular elimination decreases with decreasing temperature. In the presence of xenon this yield is also found to decrease. The fluorescence decay rate of cyclohexane and methylcyclohexane as obtained from pulse radiolysis measurements, shows a considerable temperature dependence, and is increased in the presence of xenon. The results of the photodecomposition experiments and of the fluorescence experiments are compared and discussed.
