✦ Synopsis

A brief outline of the relaxation processes leading to the spin echo amplitude decay Will be presented and discussed. Especially the role of the dipole-dipole interaction between electrons and the surrounding nuclei of a matrix will be described as an important mechanism for solids with a low concentration of paramagnetic centers. The problem of the phase relaxation and phase memory time T M will be shown for radical SeOj-center in (NH4)3 H(SeO4)2 and Cu(II) ions in triglycine selenate crystals. The results of temperature TM measurements for these crystals are shown in the Figs 1 and 2.

CrO~-radicals are produced by X-rays in (NH4) 3 H(SeO4)2 crystals doped with (NH4) 2 CrO4. The unpaired electron of CrO 3-center is located in the 3d orbital of the Cr 5+ ion. This paramagnetic center was used for monitoring by EPR the high temperature superionic phase transition of the crystal. We

Spin-lattice relaxation time, T, of tan01 (protonated and deuterated), in crystal matrix of &hydroxy-2,2,6,6-tetramethylpiperidine has been studied in the range IO-300 K. Continuous saturation technique was applied to inhomogeneous broadened ESR signals. For tanol-p a transition was observed at 133
