Abstract

Rotational relaxation cross section measurements were made for J = 0, 1 and 2 rotational states of OCS using a beam maser spectrometer. Individual rotational states were selected using electrostatic fields and cross sections for scattering and relaxation of these states by polar and non-polar scattering gasses were obtained. The angular resolution was carefully controlled so that cross sections can be compared for the different rotational states. An analysis of dipolar contributions to scattering cross sections in terms of relaxation matrix elements is presented and this is consistent with some of the observed differences in pure-states cross sections.
