Rotational relaxation cross sections for the 220, 2 21, and superposition states of HDO were measured using a beam maser spectrometer. Scattering gases used were H2O, D2O, HDO (50%), HCl, CH3F, NH3, OCS, CO2, N2, and Ar. For HDO-NH3 scattering, pure state cross sections were much larger than the superposition state cross section. For other scattering gases, pure state cross sections were slightly larger than the superposition state cross section.
