Geometrical representation of coherence transfer selection by pulsed field gradients in high-resolution nuclear magnetic resonance

A formalism for the calculation of suitable sequences of pulsed field gradients for signal selection in high-resolution NMR spectroscopy is presented. It is based on a geometrical interpretation of coherence transfer pathway selection by pulsed field gradients. The formalism allows the calculation o...

description A formalism for the calculation of suitable sequences of pulsed field gradients for signal selection in high-resolution NMR spectroscopy is presented. It is based on a geometrical interpretation of coherence transfer pathway selection by pulsed field gradients. The formalism allows the calculation of the suppression rates for undesired pathways and the determination of the most efficient sequence of pulsed field gradients. As an example, sequences for multiplicity filtered 13C/1H correlation experiments are calculated and analyzed.
