✦ Synopsis

We propose a new solid-state NMR technique under magic-angle spinning to recouple the dipolar interaction for a particular pair of homonuclear spins. In this method, a weak radio-frequency field is applied during the mixing time of the exchange NMR, and its frequency and intensity are chosen to realize rotational resonance for a particular pair of spins in the tilted rotating frame. The selective recoupling is demonstrated for the dipolar interaction between the CH and CHa carbons in triply 13C-enriched lalanine, whose chemical shift difference is too small to apply the conventional rotational resonance method.

An application of the R2TR method (1995, Chem. Phys. Lett. 232, 424) to selective homonuclear polarization transfer under magic angle spinning is proposed. It is shown that, for a spinning speed fast enough to remove the maximum homonuclear dipolar coupling constant omegaD involved, the flip-flop an

The present paper reports the achievement of the rotating-frame analog of spin-locking and its application to the precise measurements of the spin-lattice relaxation time T(1DR) in the doubly rotating frame. After the magnetization is aligned along the resonant RF field H(1), a pulse sequence of a l
