An interpretation is given for various anomalies reported by C. C. Costain concerning the rotation spectrum of CHF 3 and CDF 3 in the excited vibrational state ν 6 = 1. These anomalies are related to an essential resonance between levels K = 0, [Formula: see text], and K = ± 2, l 6 = ±1, this resonance being accidentally strong, particularly in the case of CDF 3 .
