- Abstract
IR spectroscopy is the most amenable and promising method for the characterization of hydrogen bonding systems. Most information is obtained from the band positions of OH stretching modes which are correlated to O-H...O distances. Local disorder at cation sites coordinating the donor oxygen atom of a hydrous species can produce several absorption bands in the OH stretching region, each corresponding to a different local environment. Low-temp. phase transitions may be caused by dynamic disorder-order processes of hydrogen bonded H2O mols. and OH groups. Extremely broad OH absorption bands with maxima in the 1000 cm-1 region, which may be misinterpreted as elevated background line, are caused by very strong hydrogen bonding.
