Abstract
The method of pulsed electron double resonance (PELDOR) was used to study the kinetics of phase relaxation due to dipole-dipole spin coupling of Fremy’s radical ions and neutral nitroxyl radicals TEMPON in glassy solutions frozen to 77 K. It is shown that as compared with neutral radicals, in the case of Fremy’s radical ions, the phase relaxation kinetics deviates from the exponential one. The observed low relaxation rate of Fremy’s radical ions corresponds to electrostatic repulsion for the charged radical ions. It is shown that the relative space distribution of radical ions on the basis of the Debye-Hückel theory gives a satisfactory description of the dipole-dipole spin phase relaxation for charged radicals.
