Abstract

Vibrational predissociation spectra in the region of the OH stretch are reported for I-.(H2O), I-. HDO and the weakly bound complexes I-. H2O.Ar and I-. H2O . N-2. The I-. HDO system consists of two isomers in C-5 geometry, each displaying a similar frequency to one of the two bands observed for I-.(H2O), indicating that the motions of the two hydrogens are weakly coupled. Rotational structure is partially resolved in the 3700 cm(-1) band and assigned to Q-heads of a B-type transition. Two members of the previously observed quarter [Johnson et al., Chem. Phys. Lett. 260 (1996) 551] in I-.(H2O) around 3400 cm(-1) (corresponding to the hydrogen-bonded OH) persist upon complexation with either Ar or N-2.
