Signal enhancement of J-HMQC experiments in solid-state NMR involving half-integer quadrupolar nuclei†
Abstract
We show that for half-integer quadrupolar nuclei, the manipulation of the satellite transitions can accelerate and enhance coherence transfer to other isotopes. This novel strategy is demonstrated to improve the sensitivity of 31P-{27Al} J-HMQC experiments for a layered aluminophosphate Mu-4.
