摘要：

A 364-nm negative-ion photoelectron spectrum of CH3S- has been recorded. The electron affinity; is 1.867+/-0.004 eV. Well-resolved vibrational structure has been observed such that the C-S symmetric stretch and the C-H symmetric stretch have been measured at 725+/-15 cm(-1) and 1260+/-30 cm(-1), respectively. The spin-orbit splitting is reported at 265+/-15 cm(-1). The large spin-orbit splitting quenches the Jahn-Teller modes seen in the analogous radicals, CH3O and CF3S. (C) 2000 Elsevier Science B.V.
