Theoretical study on the rotational spectra of Ar-D2 32S complex

We report a theoretical study on the rotational spectra of Ar-(D2S)-S-32. The intermolecular potential energy surface was transformed from our latest ab initio three-dimensional potential of Ar-(H2S)-S-32. The rotational energy levels and wavefunctions of the complex were calculated by using the radial discrete variable representation/angular finite basis representation method and the Lanczos algorithm. The calculated rotational transition frequencies and structural parameters were found to be in good agreement with the available experimental values.
