Abstract

The ultraviolet absorption spectra of CH₃S and CH₂SH radicals have been measured between 215 and 380 nm using the pulse-radiolysis/kinetic-abso method. One absorption band between 250 and 300 nm and one around 215 nm have been tentatively assigned to the CH₂SH and CH₃S radicals, respectively. This spectrum has been used to measure the self-reaction rates of these radicals. Rate constants of 4 × 10^-11 and 7 × 10^-11 cm³ molecule^-1 s^-1 have been measured at 298 K for CH₃S and CH₂SH recombination, respectively. The possible reaction pathways are discussed.
