    Polarized Raman spectra of single-crystal barium nitroprusside trihydrate, Ba[Fe(CN)5NO]·3H2OA communication on this subject was presented at the Xth Congress and General Assembly of the IUCr, Bordeaux, France, 19-28 July 1990. (1992)

    Notes: The room-temperature polarized Raman scattering of single-crystal Ba [Fe(CN)5NO] · 3H2O, space group Pbcm (D112h, No. 57), in the 2200-10 cm-1 spectral range, and a factor group analysis of the nitroprusside anion vibrational modes are presented. The near parallelism between the anion NCFeNO axis and a crystallographic axis facilitates the interpretation of the spectra. The data obtained complement already existing IR studies and the two series of results together provide reference information for the understanding of the vibrational behaviour of the recently reported electronically excited metastable states of the anion. The Raman data confirm the existence of a relatively large correlation (Davydov) splitting between NO stretching modes due to vibrational coupling between neighbouring nitrosyl groups in the lattice.

    Notes: Aqueous solutions of (NH4)2MoS4 have been investigated with Ar+ laser excitation, at frequencies which span the visible absorption spectrum. Enhanced values of the anti-Stokes/Stokes intensity ratios for the fundamental ν1 and overtone 2ν1 show that the Nafie et al. theory accounts satisfactorily for these observed ratios.

    The temperature dependence of the low frequency modes in the Raman spectra of ammonium perrhenate and potassium perrhenate (1981)

    Notes: The temperature dependence of the Raman spectrum of potassium perrhenate is reported. Some new detailed results on the temperature dependence of the low frequency Raman bands of ammonium perrhenate are also presented. The frequency versus temperature plots for both internal and external modes of the ReO4- ion in KReO4 appear to be linear over the temperature range from 20 to 300 K. This is in contrast to the non-linear behaviour of the external modes of the ReO4- ion in NH4ReO4. A crossing of the frequencies of the Ag and Eg librational modes of the ReO4- ion in NH4ReO4 occurs near 200 K, the temperature at which anomolies have been observed in the temperature dependence of several physical properties of this salt. The apparent discontinuities near 200 K in the slopes of the wavenumber versus temperature curves reported earlier1 are now shown to be shoulders on smooth curves. Extrapolation of the frequency versus temperature plots of the Eg and Bg translational modes of the ReO4- ion in KReO4 indicates that a crossing of the curves would occur at about 500 K, while for NH4ReO4 the crossing of the frequencies of these modes is observed near 200 K. The significance of these observations with respect to the structure and a possible higher order phase transition in the NH4ReO4 crystal is discussed.

    Notes: The Raman spectra of bromine and iodine adsorbed on 5A and 13X zeolites from carbon tetrachloride solutions presented bands that were assigned to chemical and physical adsorption. Using a rotating cell and an oscillating optical system it was possible, choosing a convenient laser power, to aid the bands due to chemisorption.

    Notes: The resonance Raman effect in solid Na5[Cu(HIO6)2].16H2O at room temperature was investigated and the experimental excitation profiles were obtained. From the analysis of the overtone progression of the ν1(A1g) mode, corresponding to the I—O symmetric stretching vibration, the X11 anharmonicity constant was determined. The dependence of the Raman intensities on the scattered frequency is briefly discussed.

    The Raman and infrared spectra and normal coordinate analysis for 1,2-diiodotetrafluorobenzene (1983)

    Notes: The Raman spectrum of 1,2-diiodotetrafluorobenzene was recorded in the region 50-2000 cm-1 on a Jarrell-Ash Model 25-300 double monochromator spectrometer using 5145 Å radiation from an argon-ion laser. The depolarization ratios of the Raman lines were measured in CS2 and CHCl3 solutions. The infrared spectrum was recorded in CS2 and CHCl3 solutions in the region 180-200 cm-1 on a Perkin-Elmer 180 spectrometer using a CsI cell. The fundamental vibrations were assigned on the basis of the frequencies and relative intensities of the bands observed in the Raman and infrared spectra and the depolarization ratios of the Raman lines. A normal coordinate analysis was also performed to check the vibrational assignments.
