چکیده
A new solid-state MAS NMR experiment is proposed to accurately measure heteronuclear (19)F-(207)Pb J-coupling constants, even though these couplings are not visible on high speed (19)F 1D MAS spectra; in particular, we demonstrate that the J-resolved experiment combined with scalar multiple-quantum filtering considerably improves the resolution of J-multiplet patterns for dilute spin systems.

Dipolar Recoupling and Decoupling
In solid state nuclear magnetic resonance spectroscopy, the magic angle spinning technique is often used to remove anisotropic interactions and generate high resolution spectra. However, these interactions contain valuable information about molecular structure and dynamics. In particular, the dipole-dipole coupling strength between two spin-1/2 nuclei is a direct reflection of their interatomic...
متن کاملFrequency selective heteronuclear dipolar recoupling in rotating solids: accurate (13)C-(15)N distance measurements in uniformly (13)C,(15)N-labeled peptides.
We describe a magic-angle spinning NMR experiment for selective (13)C-(15)N distance measurements in uniformly (13)C,(15)N-labeled solids, where multiple (13)C-(15)N and (13)C-(13)C interactions complicate the accurate measurement of structurally interesting, weak (13)C-(15)N dipolar couplings. The new experiment, termed FSR (frequency selective REDOR), combines the REDOR pulse sequence with a ...
متن کاملA SHARP Method for High-Resolution NMR of Heteronuclear Spin Systems in Inhomogeneous Fields
We describe experiments which provide sharp chemical-shift spectra, with or without scalar couplings, for heteronuclear spin systems in inhomogeneous fields. This adds to an array of conceptual developments, beginning with the work of Maudsley and Ernst (I), which has broadened the applicability of heteronuclear NMR as a probe of complex molecules and mixtures. Sensitivity has been improved by ...
متن کاملHigh-resolution NMR spectroscopy in inhomogeneous fields via intermolecular multiple-quantum coherences between spin 1/2 and quadrupolar nuclei
Introduction In inhomogeneous fields, high-resolution NMR spectra can be achieved via homonuclear intermolecular multiple-quantum coherences (iMQCs) [1-3]. We ever proposed SEL-HOMOGENIZED, IDEAL and iDQF-HOMOGENIZED pulse sequences for this purpose [2-4]. To simplify the 2D spectra, selective RF pulses were used, which make them not applicable when the chemical shifts of solvent and solute are...
متن کاملSensitivity- and gradient-enhanced hetero (omega1) half-filtered TOCSY experiment for measuring long-range heteronuclear coupling constants.
An enhanced version of the X (omega1) half-filtered TOCSY experiment for measurement of long-range heteronuclear coupling constants is proposed which yields high-quality spectra with substantially increased sensitivity and resolution. The modified method features gradient-enhanced X filtering sequences, broadband homonuclear decoupling during t1, optional 1JXH scaling in the F1 domain, and grad...
