Abstract

In situ spectroscopy and calculations agree on the characterization of the pyrolytically produced CH3S. and CH3O. radicals. The complete HeI-PE spectra of both radicals are in agreement with density functional theory calculations in both the position, shape, and intensity of the bands. The different ionized states for both radicals (three of them in the lower energy region resulting from ionization of the HOMO) are, therefore, unambiguously assigned.
