Photoelectron spectra of a number of sulfur-containing negative ions have been measured, and the following electron affinities are reported: EA(S/sub 2/) = 1.670 +/- 0.015 eV, EA(HS/sub 2/) = 1.907 +/- 0.023 eV, EA(DS/sub 2/) = 1.912 +/- 0.015 eV, EA(CH/sub 3/S/sub 2/) = 1.757 +/- 0.022 eV, EA(CD/sub 3/S/sub 2/) = 1.748 +/- 0.022 eV, EA(CH/sub 3/CH/sub 2/S) = 1.947 +/- 0.013 eV, EA(CH/sub 3/SCH/sub 2/) = 0.868 +/- 0.051 eV, EA(CH/sub 3/S) = 1.871 +/- 0.012 eV, and EA(CH/sub 2/S) = 0.465 +/- 0.023 eV. For the first five anions, the photoelectron spectra consist of excitation of the S-S stretching mode of the radical. Wherever possible, the spectroscopic information obtained is used to elucidate geometries and thermochemistry of these reactive intermediates. Results from these sulfur-containing ions and radicals are compared with what is known about their oxygen analogues.
