Adiabatic pulses for wideband inversion and broadband decoupling
TLDR

TL;DR: To rationalize the different optical properties observed, density functional theory calculations were performed for the three clusters giving straightforward explanation for the different luminescence thermochromism observed, which is attributed to different contributions of the ligands to the molecular orbitals.

Quadrupolar nuclear magnetic resonance spectroscopy in solids using frequency-swept echoing pulses
TL;DR: Some of the opportunities that arise upon departing from standard spin-echo excitation approaches and switching to echo sequences that use low-power, frequency-swept radio frequency (rf) pulses instead are discussed.

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.

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.
