The F+ CH3SSCH3 reaction has been studied by He I photoelectron spectroscopy and is seen to proceed via two competing routes, a hydrogen atom abstraction channel to generate the CHsSSCHz radical, and an adduct channel, where the adduct unimolecularly decomposes to generate CH3SF and CH3S. A weak broad band with adiabatic and vertical ionization energies of 7.00 & 0.07 eV and 7.45 f 0.03 eV, respectively, appearing at short ...
