Ultraviolet absorption spectra and kinetics of CH3S and CH2SH radicals

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

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.
