Infrared Absorptions of the H20 H2 Complex Trapped in Solid Neon

Abstract

When a sample of neon to which have been added less than 1% each of H2 and H2O is deposited at 4.3 K, the infrared spectrum of the resulting solid includes an absorption by the vibrational fundamental of H2, which is normally infrared-inactive. New absorptions are also associated with the vibrational fundamentals of the H2O in the sample. Similar results are obtained for deuterium-enriched samples. The new peaks are assigned to the van der Waals complex of H2O with H2. As has been found in earlier theoretical, gas-phase, and solid-state studies of this and closely related systems, the infrared absorptions arise principally from complexes involving ortho-H2, for which J = 1.
