Clustering of water molecules (monomer, dimer, polymer) in several kinds of gases

Abstract

Infrared spectroscopy was used to study the clustering of water molecules in various gases. H/sub 2/O molecules in the gases are shown to be trapped by other H/sub 2/O molecules or gas molecules. The interaction between water and gas molecules is strong in O/sub 2/ and He and weak in vacuum, N/sub 2/, and Freon-22. The clusters of H/sub 2/O molecules in gases are classified into monomer, dimer, and trimer. Their ratios are 55, 35, and 10%. The ratio does not change with the gas temperature and type of gas. >
