✦ Synopsis

A theoretical and experimental study of multiplet effect in spin-lattice relaxation has been undertaken. It is found that measurements of the effect in A spectra of AX* and AX3 systems provide the possibility of the direct determination of cross-correlation times.

diagonal elements of the density matrix have to be accounted for. To overcome this difficulty we used the Bloch-Redfield equation in the so-called Liouville space [6,7], i.e., in the representation with the density matrix expanded in terms of the orthogonal operators:
