MICROWAVE-SPECTRUM AND STRUCTURE OF DISULFUR DICHLORIDE, S2CL-35(2)

The microwave spectrum of disulfur dichloride, S2 35Cl2, has been studied in the frequency range 9-39 GHz. The Q-branch transitions were assigned with the aid of a diagram (similar to the Loomis-Wood diagram) specifically designed for Q-branch assignment. The assignment of some of the R-branch transitions was confirmed by means of the double resonance method. The rotational and centrifugal distortion constants were obtained. The r0 structure of this molecule was evaluated with the SCl distance fixed to the electron diffraction value. The structure thus obtained agrees well with that deduced in the electron diffraction study. © 1979.
