Abstract

The photodetachment of OH− and OD− ions has been studied in the range 7000–6450 Å, utilizing a tunable, narrow-bandwidth (0.5–1 Å) dye laser as the light source. A detailed comparison of the observed cross section with model calculations is made, yielding the following results: E.A.(OH)=(14 723±15) cm−1, E.A.(OD)=(14 703±15) cm−1. The observed isotope effect for the electron affinity can be ascribed almost entirely to differences in the position of the ground rotational state in OH(2Π3/2) and OD(2Π3/2); the implications of this result for the vibrational frequency of the negative ions are discussed. The energy dependence of the observed cross section indicates the influence of the electron-permanent dipole moment interaction in the final channel on the threshold behavior, which is found to be sharper than that expected in the absence of such an interaction.
