dc.description.abstract <p>In the energy sudden (ES) approximation for nonreactive molecular collisions,there exist factorization relations by which an arbitrary <em>T</em>‐matrix element can be predicted as a spectroscopic linear combination of those out of some other, input state. These were first discovered for ground state input but this restriction was later removed. This general form of the spectroscopicfactorization relations is straightforwardly extended here to ES dissociativecollisions. One finds that in predicting dissociation amplitudes out of some state, it is necessary to use input data out of a higher (energy) bound state. Thus ground state factorization relations <em>cannot</em> be used. The structure of two natural forms of the factorization relation coefficients (equivalent by virtue of ES consistency conditions among <em>T</em>‐matrix elements out of a single state) are analyzed in detail for a collinear atom‐truncated square‐well diatomic oscillatorsystem. Relevance of these results to the prediction of (dissociative) state specific vibrational enhancement/inhibition is discussed.</p>
