    Notes: Stokes and anti-Stokes components in the lattice vibrational laser excited Raman spectrum of a polycrystalline sample of pyridine-N-oxide are reported. The six prominent peaks at 108, 80, 71, 49, 36 and 20 cm-1 have been tentatively assigned to librational and translational lattice oscillations of the molecule.

    Optical phonons in α-NiSO4·6H2O single crystal (1974)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: Laser excited Raman spectra of a single crystal of α-NiSO4·6H2O have been attributed to the phonons originating only from the Raman active modes of isolated H2O (C2v), SO42- (Td) and Ni(H2O)62+ (Oh) units. It has been shown that Th symmetry considered earlier for NI(H2O)62+ complex by Jager and Schaack is not consistent with the crystal structure of α-NiSO4·6H2O and results in an erroneous symmetry classification of 288 phonon branches of the unit cell. A correct classification of these branches is reported. It is inferred that the SO42- and Ni(H2O)62+ polyhedra do not show large distortions from their respective Td and Oh symmetries at room temperature.
