Raman OH stretching vibration of ice Ih

Abstract

From our recent research on ice Ih (hexagonal ice), we deduce that free OH groups exist at the ice surface and that dangling OH influences the interior of the proton-disordered ice. Additionally, exploiting recent research by others on water molecular clusters, we propose a new interpretation for the Raman OH stretching vibration of ice Ih. We deconvolute the Raman OH stretching vibration of ice Ih into four sub-bands, with each sub-band being ascribed to OH vibrations engaged in different types of hydrogen bonding.
