The constants of hyperfine coupling between an unpaired electron and natural occurrence 13C have been registered for the representative series of trityl radicals. The analysis of hyperfine ac constantsrevealed their small if any dependence both on solvent, and origin and number of substituents attached at para-C atoms of TAM aromatic rings.

Keywords:
trityl radicals, EPR, hyperfine coupling, spin probes and labels.
