Argon predissociation spectroscopy of the OH(super -).H2O and Cl(super -). H2O complexes in the 1000-1900 cm(super -1) region: Intramolecular bending transitions and the search for the shared-proton fundamental in the hydroxide monohydrate

Argon predissociation spectroscopy is used to observe the first vibrational spectra of the OH(super -).H2O and Cl(super -).H2O complexes in the 1000--1900 cm(super -1) energy region. The extension to lower energy allows the exploration of the spectral signatures of the intramolecular bending fundamentals (v2) of the bound water molecule, as well as, in the strongly bond systems such as OH(super -).H2O, the motion of the shared proton.
