Interchange energy density, model

The use of the term vibrational predissociation in the above sense is not universal. Herzberg (1967) and others (Kelley and Bernstein, 1986) use VP and statistical RRKM dissociation interchangeably. The suggested use here makes the connection between vibrational and electronic predissociation stronger. In both cases, the reaction can be modeled via coupling of only two or three potential energy surfaces. The full density of vibrational states is not considered in such predissociation models.
