Summary
We present the results of a calculation of the spin-lattice and spin-spin relaxation for dipolar solid when it is irradiated by the WAHUHA and MREV-8 pulse sequences. The spin-spin relaxation rate which is determined by the second-order dipolar interaction term of the average Hamiltonian depends on thermal motion of four atoms. It has been shown that from the temperature dependence of this relaxation rate the degree of correlated atomic motion can be estimated.
