Improved Measurement of 3J(Hαi, Ni+1) Coupling Constants in H2O Dissolved Proteins

TL;DR: Permi et al. as mentioned in this paper proposed a modification to the α/β-HN(CO)CA-J TROSY pulse sequence to obtain 3 J (H α i, N i + 1 ) coupling constants from a single E.COSY-type cross-peak pattern rather than from two 1 H α spin-state-edited subspectra.

Ultrafast NMR diffusion and relaxation studies

TL;DR: In the ultrafast Laplace NMR (UFLNMR) as mentioned in this paper, the various evolution times are encoded into layers of the sample, which enables one to measure multidimensional data in a single scan, reducing the experiment time by three orders of magnitude.

Hydrogen-Bonding Interactions in T-2 Toxin Studied Using Solution and Solid-State NMR

TL;DR: The findings clearly illustrate the importance of utilizing solid-state NMR for the study of biological compounds, and suggest that a more detailed study of this whole class of toxins, namely trichothecenes, should be pursued using this methodology.

Methods of, and apparatus for, proton decoupling in nuclear magnetic resonance spectroscopy

TL;DR: In this paper, a radio-frequency pulse is tuned to the frequency of the nuclear species, such as 1 H, to be decoupled or saturated and has a bandwidth adjusted to correspond to the entire chemical shift spectrum, minimizing the amount of radiofrequency power transmitted into a volume of the irradiated sample.

Method and apparatus for broadband decoupling in nuclear magnetic resonance with chirp pulses

TL;DR: In this article, the authors proposed a method for broadband decoupling in nuclear magnetic resonance with chirp and other RF pulses, where the sample is placed in a static field, and a first cycle of chirps pulses are generated, followed by a second cycle of pulses generated by a supercycle of the first and second cycles.

Method for exciting transverse magnetization in magnetic resonance

TL;DR: In this article, a method for exciting transverse magnetization by irradiating a nuclear spin system subjected to a constant magnetic field with a frequency-modulated rf-pulse ("chirp"-pulse) and with a further frequency-modified rfpulse (further chirppulse), for refocusing the magnetization, is characterized in that the rf pulse-(P1) and the further pulse (P2) overlap each other in time at least partially.
