Adiabatic pulses for wideband inversion and broadband decoupling
TLDR
In this article, an inversion pulse for wideband application is obtained from a simple nonlinear amplitude modulation wherein the amplitude is modulated in accord with A(t)=A 0 {1-| sin βt| n } and the entire pulse is frequency modulated such that the phase varies as φ(t) =φ 0 + 1/2 kt 2About:

Fast multidimensional NMR by polarization sharing.
Eriks Kupče,Ray Freeman +1 more
TL;DR: The speed of multidimensional NMR spectroscopy can be significantly increased by drastically shortening the customary relaxation delay between scans, and the consequent loss of longitudinal magnetization can be retrieved if ‘new’ polarization is transferred from nearby spins.

Fast broadband inversion by adiabatic pulses
TL;DR: It is shown that adiabatic pulses with tangential frequency sweeps and other frequency-modulation functions can be optimized to accomplish 13C and 1H broadband inversion using pulse lengths of 192 and 64 micro(s), respectively, at B1 strengths available with modern high-resolution probes.

TL;DR: A 1 ns resolution pulse shaping unit has been developed for pulsed EPR spectroscopy to enable 14-bit amplitude and phase modulation and the concept of a dead-time compensated prefocused pulse has been introduced to EPR with a self-refocusing of 200 ns after the end of the pulse.

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
Riqiang Fu,Geoffrey Bodenhausen +1 more
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.
