TL;DR: In this paper, the probability of the activated state is calculated using ordinary statistical mechanics, and the probability multiplied by the rate of decomposition gives the specific rate of reaction, and necessary conditions for general statistical treatment to reduce to the usual kinetic treatment are given.
Abstract: The calculation of absolute reaction rates is formulated in terms of quantities which are available from the potential surfaces which can be constructed at the present time. The probability of the activated state is calculated using ordinary statistical mechanics. This probability multiplied by the rate of decomposition gives the specific rate of reaction. The occurrence of quantized vibrations in the activated complex, in degrees of freedom which are unquantized in the original molecules, leads to relative reaction rates for isotopes quite different from the rates predicted using simple kinetic theory. The necessary conditions for the general statistical treatment to reduce to the usual kinetic treatment are given.

TL;DR: In this article, a review of electron transfer reactions is presented, focusing on the absence of bond rupture in the reaction step, which is a unique feature of purely electron-transfer reactions.
Abstract: One of the active areas in reaction kinetics during the post-war years has
been that of electron-transfer reactions. These reactions constitute one type
of oxidation-reduction process and include both chemical and electrochemical
systems. Many rate constants have now been measured (1-8) and
they have stimulated a variety of theoretical studies (9-37). The field has
been characterized by a strong interplay of theory and experiment, which
now includes the testing of theoretically predicted quantitative correlations
(34). Because of a certain unique feature of the purely electron-transfer
reactions--the absence of bond rupture in the reaction step--these correlations
are unusual. They do not have the arbitrary parameters that occur
in theoretical studies of most other reactions in chemical kinetics. This review
will be limited to purely electron transfer reactions.

TL;DR: As part of a series of evaluated sets, rate constants and photochemical cross sections compiled by the NASA Panel for Data Evaluation are provided in this paper, with particular emphasis on the ozone layer and its possible perturbation by anthropogenic and natural phenomena.
Abstract: As part of a series of evaluated sets, rate constants and photochemical cross sections compiled by the NASA Panel for Data Evaluation are provided. The primary application of the data is in the modeling of stratospheric processes, with particular emphasis on the ozone layer and its possible perturbation by anthropogenic and natural phenomena. Copies of this evaluation are available from the Jet Propulsion Laboratory.
