As a first step in the theoretical treatment of elementary processes between atoms and molecules, we are going to discuss some principal aspects of molecular collisions. In the most general description one has to consider a system of two colliding atoms or molecules P and Q, as an aggregate of nuclei and electrons interacting by Coulomb and spindependent forces; henceforth, however, the latter will be disregarded and we confine ourselves to non-relativistic theory. All particles are treated as mass points; the system is supposed to be isolated (no external forces).
