diabatic electron transfer

@E02011@ process in which the reacting system has to cross over between different electronic surfaces in passing from reactants to products. For diabatic @E02011@ the electronic @T06482@ is ≪ 1 (see @M03702@). The term non-@A00142@ has also been used and is in fact more widespread, but should be discouraged because it contains a double negation.
