A theory of excitation of a solid system by a shock is developed and is implemented using first order time-dependent perturbation theory. This allows one to study excitation by both the longitudinal fields generated in a shock and also the transverse radiation field from the accelerating atoms. This is argued to be the mechanism by which shock energy (initially translational) is converted into lattice vibrations, and finally as to how these vibrations are converted into molecular vibrations, electronic excitations or even collective excitations. Some specific examples are seen for the time harmonic transverse field portion of the problem.
