Truncated dipolar recoupling in solid-state nuclear magnetic resonance
Truncated dipolar recoupling in solid-state nuclear magnetic resonance
We describe a solid-state NMR concept for the estimation of individual spin–spin couplings in strongly-coupled homonuclear spin systems. A radiofrequency pulse sequence, synchronised with the magic-angle sample rotation recouples zero-quantum dipolar interactions as well as a frequency-dispersing interaction such as the chemical shift anisotropy. The combination of these two recoupled interactions causes the spin system to behave in an approximately weakly-coupled fashion. Individual spin–spin couplings may then be disentangled by using frequency-selective radiofrequency pulses. Theoretical results and numerical simulations are compared with experimental data for the 13C nuclei in [2H7,13C3,15N]-l-alanine.

Abstract
We describe a solid-state NMR concept for the estimation of individual spin–spin couplings in strongly-coupled homonuclear spin systems. A radiofrequency pulse sequence, synchronised with the magic-angle sample rotation recouples zero-quantum dipolar interactions as well as a frequency-dispersing interaction such as the chemical shift anisotropy. The combination of these two recoupled interactions causes the spin system to behave in an approximately weakly-coupled fashion. Individual spin–spin couplings may then be disentangled by using frequency-selective radiofrequency pulses. Theoretical results and numerical simulations are compared with experimental data for the 13C nuclei in [2H7,13C3,15N]-l-alanine.
