Abstract
Cross sections for the 111, 110, 212, and 211 rotational states and for total beam attenuation of H2CO were measured using a beam maser spectrometer. Significant inelastic scattering in the forward direction was obtained for He and CF3H. Significant inelastic contributions were not observed using H2 as a scattering gas. Observed cross sections for the 111 state are larger than those for the 110 state. The relations of the present cross sections to various models for obtaining a low excitation temperature for the 111-110 doublet of formaldehyde in interstellar space is discussed.
