A theoretical study has been made of the mechanism for the transfer of translational energy into internal energy by molecular collisions. In particular, the research con¬sidered the interaction between molecules which can combine chemically to form a covalent bond. Such an interaction is typified by the collision of a proton and a diatomic hydrogen molecule which can combine to form a stable. molecule ion, and exhibits all the desired characteristics of the phenomenon under study with a minimum of extraneous effects.
