Intramolecular forces in the water molecule in lithium sulfate monohydrate

Abstract
A study of the low−temperature infrared spectra of varyingly deuterated mulls of lithium sulfate monohydrate has afforded information on the origin of bands due to the vibrations of the water molecule in the solid. Assignments are made for the intermolecularly uncoupled modes which produce these bands in the spectrum and intramolecular coupling force constants are calculated.
