The relaxation of multiple quantum transitions in a heteronuclear three-spin system is described in terms of Redfield theory including intramolecular dipolar and chemical shift anisotropy (CSA) mechanisms. CSA-dipolar cross-correlations, interference terms between CSA terms at different nuclear site
We describe a new technique for double-quantum excitation in magic-angle-spinning NMR of powdered solids. The technique is designed to efficiently excite double-quantum coherence in the vicinity of a rotational resonance condition. The offset from rotational resonance allows the double-quantum filte
