Investigation of the central line of ~(11)B in hexagonal boron nitride by a one-dimensional single pulse nutation NMR experiment

摘要

Spin-3/2 central line intensities are calculated for any ratio of the quadrupolar coupling constant to the radiofrequency field for the one-pulse NMR experiment. The sequence is then used to obtain the quadrupolar coupling constant on a powder sample of hexagonal boron nitride. This technique is found to be particularly useful when the NMR spectrum is featureless.
