The Microwave Spectrum of Sulfur Dioxide

Abstract

The K-band microwave spectrum of sulfur dioxide has been reinvestigated with results which are in agreement with the main points of the previously reported analysis by Dailey, Golden, and Wilson. Some additional lines have been assigned, and new rotational constants have been derived which permit considerably closer agreement between observed and computed frequencies. From two of these the structural parameters r(S–O) = 1.432A and ≰ (O–S–O) = 119.53° can be obtained. The remaining discrepancy (of the order of 15 mc for ten lines involving J values up to J = 35) has been attributed to inaccuracies in the centrifugal distortion computation.

Thermodynamics of some simple sulfur-containing molecules

“…For sulfur dioxide gas, the product of the moments of inertia was taken as the average of th e microwave measurements of Dailey, G olden, and liVilson [9], who obtained 106.403 X 10-117 g3cm6, Sirvetz [10], 107.007 X 10-117 g3cm6, and Crable and Smith [11], 106.996 X 10-117 g3cm6. This product of the moments of inertia, 106.80 X lO -117 g3cm6, and the vibrational frequencies given by Herzberg [12] were used in a rigid rotator-harmonic oscillator calculation.…”

Reassignment of the OSe−VCd complex in CdSe

“…Theoretical support of this model is needed. For comparison, the free SO 2 gives rise to three vibrational modes at 518, 1151, and 1362 cm −1 of which only the latter is IR active [13,14,15,16].…”
