Reintroducing anisotropic interactions in magic-angle-spinning NMR of half-integer quadrupolar nuclei: 3D MQMAS.
Selective reintroduction of anisotropic interactions such as the chemical shift anisotropy (CSA) and homonucler dipolar (HMD) coupling were implemented in a high-resolution NMR spectroscopy for half-integer quadrupolar nuclei. Rotary resonance recoupling (R(3)) combined with the multiple-quantum magic-angle spinning (MQMAS) in a three-dimensional (3D) experiment provides not only site-specific ...
متن کاملQuadrupolar-driven recoupling of homonuclear dipolar interactions in the nuclear magnetic resonance of rotating solids
We discuss the recoupling of homonuclear dipolar interactions between quadrupolar nuclei under magic-angle spinning conditions, caused by the first-order quadrupolar interaction. This recoupling leads to NMR linewidths displaying a nonmonotonic dependence on the spinning frequency, meaning that broader lines may result as the spinning rate is increased. The effect depends on geometrical paramet...
متن کاملMultiple-quantum magic-angle spinning and dynamic-angle spinning NMR spectroscopy of quadrupolar nuclei.
Several aspects of the Multiple-Quantum Magic-Angle Spinning (MQMAS) technique (L. Frydman and J.S. Harwood, J. Am. Chem. Soc., 117 (1995) 5367) are compared with Dynamic-Angle Spinning (DAS). Examples of MQMAS spectra are shown for I = 3/2 nuclei with CQ up to 3.6 MHz, and for 27Al (I = 5/2) with CQ up to 10 MHz. The MQMAS linewidth is largely independent of the magnitude of the homonuclear di...
متن کاملResidual dipolar couplings in MAS and MQMAS NMR spectra of quadrupolar nuclei
Ž . We report the first observation of residual dipolar couplings in magic-angle-spinning MAS and multiple quantum Ž . magic-angle-spinning MQMAS NMR spectra of half-integer quadrupolar nuclei. In particular, the fine spectral splittings observed in the B MAS spectrum of crystalline triethanolamine borate are attributed to the residual B–N dipolar coupling, which is not completely averaged by M...
متن کاملHeteronuclear recoupling in solid-state magic-angle-spinning NMR via overtone irradiation.
A heteronuclear dipolar recoupling scheme applicable to I-S spin pairs undergoing magic-angle-spinning (MAS) is introduced, based on the overtone irradiation of one of the coupled nuclei. It is shown that when I is a quadrupole, for instance (14)N, irradiating this spin at a multiple of its Larmor frequency prevents the formation of MAS dipolar echoes. The ensuing S-spin signal dephasing is sig...
