The Raman and infra-red spectra of some solid hydroxides. Part II. Correlation with crystal structure

Abstract

The paper discusses the results reported in Part I in relation to the crystal structures of the substances. From a comparison of the facts with the theoretically expected picture of the spectrum, the salient features exhibited by the spectra have been explained, in addition to identification and assignment of the frequencies wherever feasible. The progressive variations in the hydroxyl shifts exhibited by the different hydroxides and their hydrates are explicable as due to the interactions of the hydroxyls with each other and also with their neighbouring water molecules in the case of the hydrates.
