I thank MPI PKS Dresden for kind hospitality, and
H.-H. Klauss and H. Kühne (TU Dresden) for helpful discussions
of the obtained results. The support from the Institute
for Chemistry of V.N. Karazin Kharkov National
University is acknowledged.
I dedicate this work to Academician Professor Viktor
Valentinovich Eremenko, who has suggested me to study
theoretical physics, and who has done so much for me, on
the occasion of his 80th birthday.

The relaxation rate of the nuclear magnetic resonance is calculated exactly for a model spin-1/2 chain with
the magnetic impurity. It is shown that the deviations of the impurity's coupling to the chain and the effective
impurity's g-factor from the values of the host chain yield special features in the temperature and magnetic field
behavior for the relaxation rate.
