Selective internuclear coupling estimation in the solid-state NMR of multiple-spin systems
Selective internuclear coupling estimation in the solid-state NMR of multiple-spin systems
A new solid-state NMR method is presented for estimating homonuclear dipole–dipole couplings for selected groups of nuclear spins in a multiple-spin coupled network. The methodology combines off-magic-angle spinning, frequency selective spin echoes, and multiple quantum filtering. The new method is insensitive to incoherent relaxation effects and may be used to estimate weak couplings. Internuclear 13C–13C couplings are estimated in uniformly 13C-labelled L-Histidine·HCl·H2O. Weak intermolecular couplings between 13C nuclei separated by distances exceeding 6 Å are estimated.

Abstract
A new solid-state NMR method is presented for estimating homonuclear dipole–dipole couplings for selected groups of nuclear spins in a multiple-spin coupled network. The methodology combines off-magic-angle spinning, frequency selective spin echoes, and multiple quantum filtering. The new method is insensitive to incoherent relaxation effects and may be used to estimate weak couplings. Internuclear 13C–13C couplings are estimated in uniformly 13C-labelled L-Histidine·HCl·H2O. Weak intermolecular couplings between 13C nuclei separated by distances exceeding 6 Å are estimated.
