The laser excited Raman spectrum of MnCl 2 ·2H 2 O has been reported in the 4000–150 cm −1 region and discussed in conjunction with the known IR spectra. The bands have been assigned to internal and librational modes of water and other lattice modes. It has been found that the correlation splitting parameter Δ ν/ν mean is distinctly larger for the librational modes than for the internal modes of water. The increase in intensity of the ν 1 over the ν 3 band of water in passing from the free to crystal water state and the low intensity of the librational bands have been explained.
