Sa. Dzuba et al., DIPOLAR INTERACTIONS OF SPIN PROBES IN ORGANIC GLASSES STUDIED BY ELECTRON-SPIN ECHO, Chemical physics letters, 214(6), 1993, pp. 621-626
A novel electron spin echo method, employing selective hole-burning in
EPR spectra with subsequent detection of free induction decay and ech
o temporal shape, has been applied to study dipole-dipole interactions
of TEMPO nitroxides dissolved in glassy ethanol and water-glycerol mi
xture. The results obtained suggest clustering of guest molecules in t
hese matrices.
