We study the large amplitude response of classical molecules to electromagnetic radiation, showing the universality of the transition from the linear to nonlinear response and brakeup at sufficiently large amplitudes. A range of models, from the simple harmonic oscillator to the successful Peyrard-Bishop-Dauxois (PBD) type models of DNA, lead to characteristic universal behavior: formation of domains of dissociation in the driving force amplitude-frequency space, characterized by the presence of local boundary minima...
