Abstract
The technique of four‐level microwave double resonance has been applied to the study of rotation‐inversion transitions of NH3 induced by collisions with various polar molecules. H2O, D2O, CH3OH, CH3X and CHX3 (X=F, Cl, Br, I), NO, CO, and OCS were used as collision partners. The values of η=ΔI/I observed for many four‐level systems which are connected by dipole‐type transitions (ΔJ=±1, ΔK=0, parity +↔−) are given and qualitatively explained taking into account the long‐range dipole–dipole interaction and the pattern of rotational energy levels of the collision partners.
