β¦ Synopsis
Computer-aided methods can considerably simplify the use of the product operator formalism for theoretical analysis of NMR phenomena, which otherwise becomes unwieldy for anything but simple spin systems and pulse sequences. In this report, two previously available programming approaches using symbolic algebra (J. Shriver, Concepts Magn. Reson. 4, 1-33, 1992) and numerical simulation using object-oriented programming (S.

## Abstract Coherence pathway selection with gradients in carbonβdetected experiments is demonstrated. Gradient selection (gs) offers excellent suppression of artifacts and unwanted magnetization, and in practice the signalβtoβnoise ratio is at least as good as for the equivalent phase cycled exper
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
