The effects of centrifugal distortions on polarizability anisotropics are taken into account to explain the experimental Rayleigh spectrum of H2S. Centrifugal corrections are calculated following a first-order perturbation theory due to Toyama et al. The simulated spectrum agrees with the experimental one qualitatively, but the calculated corrections to the rotational transitions are not large enough to reproduce the experimental findings. Possible origins of that discrepancy and consequences of a significant variation of the optical anisotropy are briefly discussed. © Taylor & Francis Group, LLC.
