Isotropic mixing, sign discrimination, and sensitivity in solid-state wideline heteronuclear correlation experiments.
A variant of the solid-state wideline heteronuclear NMR correlation experiment is described which overcomes some of the drawbacks associated with the routine experiment. The modified experiment results in spectra which are sign-discriminated in the omega(1) dimension, but without the loss in sensitivity expected for a standard hypercomplex implementation. In favorable cases sensitivity enhancements over comparable routine experiments are obtained. As well as these advantages, the method retains the selectivity of modified WISE experiments proposed previously which give spectra containing correlations between directly bonded nuclei only.
