- Abstract
DICKINSON and West (Phys. Rev., 35, 1126; 1930) have determined the Raman spectrum of sulphur dioxide; they obtained displacements of 524 (weak), 1146 (strong), and 1340 (medium) cm.−1. We had already examined the infra-red absorption spectrum of sulphur dioxide between 2 μ and 20 μ with a Hilger D. 42 spectrometer, using quartz, fluorite, rocksalt, and sylvine prisms, and found bands at 2498, 2321, 1871 (very weak), 1355, 1152, and 606 cm.−1; of these the band at 1355 cm.−1 is most intense and seems to possess a complicated structure. The fundamental frequencies are probably v1=1355, v2=1152, and v3=606 cm.−1. The two larger frequencies are in good agreement with those deduced from the Raman spectrum, although the scattered line at 524 cm.−1 agrees more closely with the difference between v2 and v3 (1152−606=546 cm.−1) than with v3 itself. The other bands can be accounted for as combination-and over-tones.
