Two extreme cases of the formal kinetic description are discussed. One of them is the rate constant distribution. In this case it is assumed that reagent in solids may be divided into subensembles. Each subensemble reacts according to simple kinetic

Elementary physical relaxation processes and chemical reactions proceeding under quasimonomolecular conditions are often determined by the fractional exponential law: [R] = [R] 0 exp(− K α t α ). Here [R] is the value of a relaxing parameter (con

It is shown by ESR studies that the carboxymethyl radical decay in h 4 - and d 4 -malonic acid single crystals results in the formation of CH(COOH) 2 and CD(COOD) 2 radicals, respectively. Over the ranges of 45–55°C for d 4 -acid and 0–12°C for
