The spectra structure and shape were<br />demonstrated to be dependent on regimen and composition of freezing medium. The obtained experimental EPR spectra are theoretically described by spin Hamiltonian containing axially symmetric term of fine structure with manifestation of forbidden Δm = ±1 transitions. There was proposed to use EPR approaches in designing low temperature technologies for biological object preservation to analyze freezing regimens and possible cryoprotectants to forecast the minimization of cryoinjury effects with high salt concentrations during freezing. <em></em></p><p><em><br /></em></p><p><em>Probl Cryobiol Cryomed 2014; 24(3):212-221.</em></p> ER -
