A number of different approaches may be subsumed under this heading—approaches which are not restricted to nonadiabatic reactions. In remote encounters, the initial and final states refer to separated reactants and products, respectively, and the transition probability may be computed from the corresponding energy defect this model is familiar for charge-transfer processes, but has been applied to chemical reactions. The effect of spin and symmetry conservation on such crossings has also been assessed qualitatively. The importance of the Franck-Condon overlap integral in determining the transition probability has also been treated semiempirically. In the theoretical discussion of nonadiabatic reactions, it is standard practice to compute the transition probability between the surfaces, for example, by Landau-Zener theory. ...
