Abstract
The method for calculating collision‐induced transition rates presented in an earlier paper has been applied to four‐level systems in the ammonia molecule. The transition rates in pure NH3 and in NH3 perturbed by H2, D2, HD, para‐H2, N2, and O2 are calculated. The intensity changes (ΔI/I) are derived from these rates and compared with the experimental values.Keywords
