Absorption Spectra of Solid Methane, Ammonia, and Ice in the Vacuum Ultraviolet
Abstract
The vacuum ultraviolet spectra of solid ammonia and ice are found to be shifted to higher frequencies relative to the corresponding vapor spectra by 7000 cm-1. The effects of hydrogen bonding in the ground states of these solids, and the nature of repulsive interactions possible in the excited states are discussed. In methane, which forms a pure van der Waals solid, the spectra of gas and solid are found to be very similar.
