Broadband Heteronuclear Decoupling in the Presence of Homonuclear Dipolar and Quadrupolar Interactions
نویسندگان
چکیده
A new family of composite decoupling sequences designed for heteronuclear broadband decoupling of spin-l and spin-f in solids and liquid crystals is introduced. The pulse sequences are windowless and perform net rotations in spin space about magic-angle axes. Computer simulations and experimental results are presented to demonstrate their decoupling performance and to discuss their susceptibility toward pulse imperfections. We describe the evaluation of the new sequences, called COMARO (composite magic-angle rotation), and point out some possibilities for further improvements. o 1987 Academic

Broadband Heteronuclear Spin Decoupling in Solids
While heteronuclear broadband decoupling by composite pulse sequences is a well established method in isotropic liquids [ l-41, analogous decoupling sequences for oriented systems have been introduced only recently [ 5-91. Those sequences [ 891, termed COMARO, were derived from a theoretical analysis of heteronuclear decoupling in the presence of homonuclear interactions like dipole-dipole and ...
متن کاملDipolar 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 کاملHeteronuclear decoupling interference during symmetry-based homonuclear recoupling in solid-state NMR.
We examine the influence of continuous-wave heteronuclear decoupling on symmetry-based double-quantum homonuclear dipolar recoupling, using experimental measurements, numerical simulations, and average Hamiltonian theory. There are two distinct regimes in which the heteronuclear interference effects are minimized. The first regime utilizes a moderate homonuclear recoupling field and a strong he...
متن کاملSolid state separated-local-field NMR spectroscopy on half-integer quadrupolar nuclei: principles and applications to borane analysis.
New multidimensional NMR methods correlating the quadrupolar and heteronuclear dipolar interactions affecting a half-integer quadrupolar spin in the solid state are introduced and exemplified. The methods extend separated-local-field magic-angle spinning (SLF MAS) NMR techniques that have been used successfully in spin-(1)/(2) spectroscopy to the study of S >/= (3)/(2) nuclei. In our implementa...
متن کاملTriple oscillating field technique for accurate measurements of couplings in homonuclear spin systems
We present a new concept for homonuclear dipolar recoupling in magic-angle-spinning (MAS) solid-state NMR experiments which avoids the problem of dipolar truncation. This is accomplished through the introduction of a new NMR pulse sequence design principle: the triple oscillating field technique. We demonstrate this technique as an efficient means to accomplish broadband dipolar recoupling of h...
