Abstract
Hydrogen atoms have been detected by time-resolved resonance fluorescence spectroscopy following 248-nm pulsed-laser photolysis of CH3SH. The primary photolysis yield of H atoms has been determined to be 1.08 ± 0.24 by comparing fluorescence signals observed following CH3SH photolysis with those observed following photolysis of O3/H2 mixtures. The kinetics of the H + CH3SH reaction have been investigated. Over the temperature range 249-405 K the rate constant is given by the Arrhenius expression k = (3.45 ± 0.13) × 10-11 exp[-(845 ± 12)/T] cm3 molecule-1 s-1.
