Marcus theory Originally introduced by R. A. Marcus in 1956 as a method for calculating rates of electron transfer in outer-sphere processes. It has since been extended and refined significantly to address a variety of different types of transformations. Where has this theory found the most utility?

In theoretical chemistry, Marcus theory is a theory originally developed by Rudolph A. Marcus, starting in 1956, to explain the rates of electron transfer reactions – the rate at which an electron can move or jump from one chemical species (called the electron donor) to another (called the electron acceptor ).

Learning theory, any of the proposals put forth to explain changes in behaviour produced by practice, as opposed to other factors, e.g., physiological development. A common goal in defining any psychological concept is a statement that corresponds to common usage. Acceptance of that aim, however,

May 26, 2023 · 11.2.6.8: Marcus Theory. Page ID. In classical transition-state theory, the expression for the rate constant of a bimolecular reaction in solution is. k = (κνn) − ΔG ∗ RT, where νn, the nuclear frequency factor, is approximately 10 11 M -1 s -1 for small molecules, and Δ G* is the Gibbs-free-energy difference between the activated ...
The Marcus Theory of Electron Transfer. A great many important aspects of biology and biochemistry involve electron transfer reactions. Most significantly, all of respiration (the way we get energy from food and oxygen) and photosynthesis (they way plants make the food and oxygen we consume) rely entirely on electron transfer reactions between ...

Abstract. Learning is a fascinating phenomenon that attracts from very different perspectives ample research attention. This section of the major reference work handles from a myriad of perspectives that fascinating phenomenon. Rather than introducing each of the contributions, this introduction provides an overview of major topics addressed ...
It is well-known that fewest-switches surface hopping (FSSH) fails to correctly capture the quadratic scaling of rate constants with diabatic coupling in the weak-coupling limit, as expected from Fermi’s golden rule and Marcus theory. To address this deficiency, the most widely used approach is to introduce a “decoherence correction”, which removes the inconsistency between the wave ...
