Adiabatic pulses for wideband inversion and broadband decoupling
TLDR

Practical aspects of 15N CPMG transverse relaxation experiments for proteins in solution
TL;DR: This study simulated 15N CPMG relaxation in the presence of either 1H composite decoupling or 1H 180° pulses and compared the results with the experimental transverse relaxation data acquired with [u-15N]- or [u -15N, u-2H]-ubiquitin samples.

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 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.
