Abstract

Photodetachment of the three anions CH3O−, CD3O−, and CH3S− by a fixed-frequency argon ion laser at 488 nm and subsequent energy analysis of the photoelectrons yields the photoelectron spectra of these species. From the spectra, electron affinities were determined: E.A.(CH3O) = (1.570±0.022) eV, E.A.(CD3O) = (1.552±0.022) eV, E.A.(CH3S) = (1.882±0.024) eV. From the vibrational structure appearing in the spectra, and the shifts observed upon deuteration, the predominant motion excited in the neutral upon photodetachment of CH3O− and CD3O− is found to be the symmetric hydrogen umbrella bend at 1325±30 and 1010±30 cm−1, respectively. In CH3S both the symmetric hydrogen bend and the carbon–sulfur bond stretch (680±40 cm−1) are excited. From the observed hot bands, some vibrational frequencies of the negative ions are also derived.
