摘要：

The photoelectron spectra of the methoxide anions, CH3O- and CD3O-, have been measured at 8-10 meV resolution. The spectra show resolved vibrational structure corresponding to vibrational levels of the CH3O/CD3O (X) over tilde(E-2) state. These vibrational progressions are assigned to the degenerate nu(5) and nu 6 modes of the methoxy radical; no progressions in the totally symmetric stretch modes are observed. In addition, we obtain refined electron affinities: EA(CH3O)= 1.568 +/- 0.005 and EA(CD3O) = 1.551 +/- 0.005 eV. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
