“…So, we shall only discuss in this paper results obtained with liquid solutions in order to avoid spectroscopic crystal effects. The spectrum of pure DMSO 2 (solution a) is identical to those already published. In particular, two strong lines are observed for the symmetric stretching vibrations ν s SC 2 and ν s SO 2 , at 695 and 1130 cm -1 respectively, which can be regarded as practically pure modes. , Moreover, the five bands of medium intensities corresponding to the bending modes of the tetrahedron are detected between 300 and 500 cm -1 .
1 Raman spectra of molten dimethylsulfone solutions a−e at 400 K.

“…3 Dimethyl sulfone is, in addition to methane sulfonic acid, a product of dimethyl sulfide oxidation. The infrared spectrum of (CH 3 ) 2 SO 2 was previously recorded in the crystalline, 4 gas phase [4][5][6] and liquid 6 states. No reports of the matrix isolated spectrum were found.…”

“…are (i) depletions of the assigned[23][24][25][26] bands at 560 cm À1 (SO 2 scissoring), 840-880 cm À1 (C-C, C-H and C-O deformation), 1110 and 1160 cm À1 (S]O and C-O stretching) and 1490 and 1580 cm À1 (C-H deformation and C]C stretching) modes and (ii) a build-up of the bands at 650-690 cm À1 that belong to C-S stretching mode. There is no growth of bands at 3300-3600 cm À1 (O-H stretching) and 1300-1400 cm À1 (OH deformation) indicative of hydroxyl group.…”
