RRKM theory
Encyclopedia
The Rice–Ramsperger–Kassel–Marcus (RRKM) theory of chemical reactivity was developed by Rice and Ramsperger in 1927 and Kassel in 1928 (the RRK theory). The RRK theory was generalized into the RRKM theory in 1952 by Marcus

Rudolph A. Marcus
Rudolph "Rudy" Arthur Marcus is a Canadian-born chemist who received the 1992 Nobel Prize in Chemistry for his theory of electron transfer. Marcus theory, named after him, provides a thermodynamic and kinetic framework for describing one electron outer-sphere electron transfer.He was born in...
who took the transition state theory
Transition state theory
Transition state theory explains the reaction rates of elementary chemical reactions. The theory assumes a special type of chemical equilibrium between reactants and activated transition state complexes....

Potential energy surface
A potential energy surface is generally used within the adiabatic or Born–Oppenheimer approximation in quantum mechanics and statistical mechanics to model chemical reactions and interactions in simple chemical and physical systems...
