TL;DR: In this paper, a simple product operator description of the strongly coupled AB and ABX spin systems is developed, and the utility of this description in the investigation of the effects of strong coupling is illustrated in a number of examples.

TL;DR: In this paper, a 2D DEPT heteronuclear shift correlation maps for cholesterol in CDCl 3 are reported and demonstrate the selectivity and utility of these experiments, and an implementation in which the 2D data files for proton flip angles τ = 30, 90, and 150° are acquired and used to construct selective CH, CH 2, and CH 3 maps is shown to be twice as efficient as the previous implementation where separate experiments were performed to construct each selective 2D map.

TL;DR: The product operator description of magnetic resonance experiments is developed in the spherical-tensor basis, and a computer simulation scheme, employing this description, is reported in this article, where the utility of simulations in the design of selective phase cycles and in the study of the effects of spectrometer imperfections is demonstrated.

TL;DR: In this paper, the dependence of the rotating-frame relaxation rate (R1ϱ) of bulk solvent nuclei on the magnitude of the spin-locking field H 1 = − ω 1 γ for a dilute solution of a paramagnetic ion dissolved in a solvent which undergoes exchange between bulk and coordinated sites was investigated.
