In the ESR spectra of 6-triphenylmethyl-4-tert-butyl-2-hydroxyphenoxy and 6-triphenyl-mehyl-4-phenyl-2-hydroxyphenoxyl and their deuterated analogs, temperature-dependent dynamic effects have been found; these are explained from the standpoint of a reversible intramolecular transition between different conformations of the radicals, differing in the spin density distribution, owing to direct interaction of the unpaired electron with the orbitals of the phenyl rings of the triphenylmethyl substituent.
