Low wavenumber Raman bands (300-25 cm −1) and isotope effects for eight isotopically substituted lithium formate monohydrates LiX′CO 2·X″ 2O

Abstract

The Raman spectra of eight isotopically substituted lithium formate monohydrates, LiX′CO 2·X″ 2O, were investigated in the wavenumber region from 300 to 25 cm −1. The observed spectral data were assigned to the X′CO − 2 and X″ 2O lattice modes and discussed taking the isotope effects on the fundamental bands into account.
