N2 - Phonon instabilities are examined in a simple model hamiltonian involving two electronic states coupled to a single phonon mode. When the transition between electronic states is pumped by an external source, the phonon mode can be driven into coherent oscillation; in polymer systems this coherence may extend over macroscopic distances. Experimental situations in which such macroscopic coherence might be observed are considered.
