Sja. Pope et Yd. West, COMPARISON OF THE FT RAMAN-SPECTRA OF INORGANIC TETRAHEDRAL IONS OVERTHE TEMPERATURE-RANGE 77 TO 473 K, SPECT ACT A, 51(12), 1995, pp. 2027-2037
The vibrational spectra recorded over a wide temperature range (77-473
K) of a number of inorganic transition metal salts containing tetraox
yanions in both solution and crystal phases are reported. All modes in
these cases are Raman active and the bands predicted by site-symmetry
analysis are observed. Only bands assigned as nu(3) and nu(1) are fou
nd to be temperature dependent. The significance of this is discussed.
