Weak Raman bands from water
G. E. Walrafen,L. A. Blatz +1 more
TLDR
Weak, broad, Raman bands have been observed from water and heavy water at shifts above and below those corresponding to the intramolecular bending and stretching vibrations of D2O and H2O molecules that are either partially, or fully hydrogen bonded.Abstract:
Weak, broad, Raman bands have been observed from water and heavy water at shifts above and below those corresponding to the intramolecular bending and stretching vibrations. Bands near Δv = 1190 cm−1 for D2O and Δv = 1625 cm−1 for H2O, in addition to relatively sharp bands at 1210 cm−1 for D2O and 1640 cm−1 for H2O are thought to arise from intramolecular bending vibrations of D2O and H2O molecules that are either partially, or fully hydrogen bonded. Other weak bands can be explained as combinations of known intra‐ and intermolecular vibrations, in particular, librations.read more

Raman Spectral Studies of HDO in H2O
TL;DR: In this article, a 6.2M solution of D2O in H2O was analyzed by means of a specialpurpose analog computer, and two Gaussian components near 2510−2540 and 2630−2660 cm−1 were found to provide adequate fits of the contours in the temperature range involved, although some indication of a third weak Gaussian Raman component was found.

Low-Frequency Raman Lines from Liquid Benzene, Benzene Derivatives, and Other Organic Liquids
TL;DR: In this article, the depolarization ratios of low-frequency Raman lines from benzene and toluene (also carbon tetrachloride) were investigated. But the results can be interpreted on the basis of a somewhat disordered solid structure for liquid benzene, and for some other liquids.
