(1)H-detected two-dimensional double-/zero-quantum experiments are described for measurement of homonuclear (2)J(HH)-couplings of NH(2) or CH(2) groups in proteins. These experiments utilize multiple-quantum coherence for determination of the size and the absolute sign of the geminal scalar and dipo
The distributions of both the quadrupolar and the isotopic chemical shift interactions are shown to give multiple-quantum MAS spectra that remain tilted after shearing. For both types of distribution, the theoretical slopes, formed by the resulting distribution of the centers of gravity of the signa
A method for the inclusion of the effects of z-axis pulsed field gradients in computer simulations of an arbitrary pulsed NMR experiment with spin 1 2 nuclei is described. Recognizing that the phase acquired by a coherence following the application of a z-axis pulsed field gradient bears a fixed rel
