Dissociation of a Diatomic Gas
... Let us consider the following simple model for a diatomic gas: a diatomic molecule consists of a pair of point-like atoms, each of mass m, separated by a rigid rod of length a. The rigid rod corresponds to the chemical bond, which requires an energy to break. Now, at any finite temperature T , we ...
