The strong‐coupling correspondence principle has been used to calculate the T – V transition probabilities in the collinear collision of He and Kr with CO 2 . For a harmonic CO 2 potential the results for He agree well with published quantum mechanical probabilities. For Kr the agreement is less satisfactory but at worst the ratio of quantum to semiclassical transition probability is approximately 0.2. Introduction of anharmonicity in the CO 2 potential was found to increase the semiclassical transition probabilities but this may just be due to the lowering of the vibration frequencies.
