“…The isotropic profile can be accurately extracted from Raman VV and VH spectra, as can the anisotropic spectra. The following non-polar inert solvents are known to slightly perturb the rotational motions: light alkanes [23,26], carbon tetrachloride CCI 4 and sulphur hexafluoride SF 6 [22][23][24][25][26]. The anisotropic profiles could only be calculated in CC14 and SF 6 , which are almost transparent in the studied spectral ranges.…”
