Web11.2.1 History. Relaxation methods in chemical kinetics were proposed by Manfred Eigen in the 1950s (Eigen, 1954 ). The main methodology and mathematical idea of such methods is an analysis of transient regimes, so-called relaxation, that is, the behavior of chemical systems perturbed near equilibrium. In 1967, Eigen, together with Norrish and ...
