It follows from the general theory of chemical reactions proposed by London in which diabatic potential-energy surfaces are used to describe isolated reactant and product species, these surfaces being coupled by an electronic coupling "V" ab.

These chemical reactions are proposed by London in which diabatic potential-energy surfaces are used to describe isolated reactant and product species. London in which diabatic potential-energy surfaces are used to describe isolated reactant and product species are these surfaces. These surfaces are being coupled by an electronic coupling "V" ab.
