Abstract

The conformation ofэSiOC·H2 radicals was determined by comparison of the ESR data and results of quantum-chemical calculations. Based on the experimental data, the characteristic times τc of rotational mobility ofэSiOC·H2 radicals grafted onto a silica surface were estimated over the temperature interval from 77 (τc = 15.8 · 10-8 s) to 295 K (τc 1.3 · 10-8 s).
