Abstract

Abstract: Thirty-five rate constants, k,, for transfer of hydride between various pyridinium, quinilinium, acridinium, and phenanthridinium ions spanning a range of over 10” in their equilibrium constants Kij and over lo6 in k, have been measured.(All these ions can be regarded as analogues of NAD'.) Calculation of these k, by conventional Marcus theory, with a constant, averaged value of the intrinsic barrier, A, gives a fair level of agreement, with ...
