Low wavenumberRamanbands (300−50cm−1) for four isotopically substituted lithium hydrogen oxalate monohydrates LiXC2O4·X2O

摘要

The solid stateRamanspectra (300−50 cm−1) of lithium hydrogen oxalate monohydrate have been investigated for four isotopically substituted compounds,6LiHC2O4·H2O,7LiHC2O4·H2O,6LiDC2O4·D2O and7LiDC2O4·D2O. The observed spectral data have been discussed on the basis of the factor group analysis by considering the H/D and6Li/7Li isotope effects on the fundamental lattice vib
