MLEV-17-based two-dimensional homonuclear magnetization transfer spectroscopy
Ad Bax,Donald G. Davis +1 more
TL;DR: In this article, a new mixing scheme based on the MLEV-16 composite pulse decoupling cycle (II) was proposed, which is less sensitive to pulse imperfections and provides net magnetization transfer over a substantial bandwidth with only limited rf power.

An Improved Broadband Decoupling Sequence for Liquid Crystals and Solids
TL;DR: It is found that a stepwise variation of the phase angle in the TPPM sequence offers even better results, and the application of this new method to a liquid crystalline compound and a solid, L-tyrosine hydrochloride, is reported.
Journal ArticleDOI
Computer-optimized decoupling scheme for wideband applications and low-level operation
TL;DR: In this paper, the WALTZ-16 decoupling scheme was used for carbon-l 3 linewidth modulation with a 40% improvement in bandwidth over the original Waltz-16.
Journal ArticleDOI
An improved sequence for broadband decoupling: WALTZ-16
TL;DR: In this paper, the effects of the proton irradiation sequence by means of a train of spin rotation operators, the overall effect at the end of the cycle being calculated by explicit matrix multiplication, the offset dependence of this proton response determined the residual splitting of the carbon-13 resonance and hence the effectiveness of the decoupling.
Journal ArticleDOI
Evaluation of a new broadband decoupling sequence: WALTZ-16
TL;DR: In this article, a new scheme for low-power broadband heteronuclear decoupling is described, based on the use of a composite radiofrequency pulse sequence 90°( + X ) 180°(− X ) 270°(+ X ), incorporated into a repeated cycle or supercycle.

Coherent Averaging Effects in Magnetic Resonance
U. Haeberlen,J. S. Waugh +1 more
TL;DR: In this paper, a theory is developed to describe the slow component of the transient decay of transverse spin magnetization, and the central component of slow-passage absorption spectrum, of a system of spins which is subjected to a periodic and cyclic perturbation.

Nuclear Magnetic Double Resonance with an Incoherent Radio-Frequency Field
TL;DR: In this article, the decoupling of heteronuclear spin systems by means of a strong irradiation of rf magnetic random noise is explored theoretically and experimentally, and it is shown that it is feasible to eliminate simultaneously all splittings due to one or more nuclear species.
