On collisional vibrational deexcitation rate constantsk 1?0 of diatomic molecules

Abstract

Collisional vibrational deexcitation rate constantsk 1→0 for diatomic molecules have been calculated and used by a number of authors. But sometimes scientists use some fit-formula instead of the actual expression. This may be caused by difficulties in understanding the actual formula. Here, I discuss the calculations of collisional deexcitation rate constants for diatomic molecules by using the actual expression.
