Abstract

Inelastic scattering cross sections for the upper and lower states of J=1 and J=2, K-type doublets of formaldehyde were measured using a beam maser spectrometer. Scattering gasses used were He, Ar, H₂, N₂, CO₂, HCl, NH₃, CH₃F, and CF₃H. Systematic variations in cross sections with the symmetry and dipole moments of scattering molecules are observed. Anderson's theory of pressure broadening, with slight modification, is used to interpret the data. This model gives reasonably good agreement with most of the observed effects.
