Аннотация:The conformation of =SiOC . H-2 radicals was determined by comparison of the ESR data and results of quantum-chemical calculations. Based on the experimental data, the characteristic times (tau(c)) of rotational mobility of =SiOC . H-2 radicals grafted onto a silica surface were estimated over the temperature interval from 77 (tau(c) = 15.8 10(-8) s) to 295 K (tau(c) = 1.3.10(-8) s).
