Deconstructing water’s diffuse OH stretching vibrational spectrum with cold clusters
Abstract
In principle, the surface structure of water (H 2 O) should be discernable from the O–H vibrations. In practice, however, so many configurations rapidly interconvert that the bands are bewilderingly broad. Yang et al. studied a cluster of 20 H 2 O surrounding a cesium ion, using isotopomers that vary in the position of one H 2 O amid 19 heavy water (D 2 O) molecules. Precisely assigned spectral features from contributing configurations mapped well onto a bulk surface spectrum.
