The selection of well-defined coherence transfer pathways is an essential feature of all but the simplest NMR and EPR pulse sequences. This selection can be achieved by phase cycling and by pulsed field gradients. The properties of the RF-pulses (flip angle, offset effects, inhomogeneity) and transp
A method for the construction of a coherence transfer diagram showing only the pathways selected by a particular phase cycle is presented. The concepts of coherences and coherence levels and their association with product operators in the spherical tensor basis are introduced. The encoding of cohere
