A 3D experiment that provides isotropic homonuclear correlations of half-integer quadrupolar nuclei

- We combine MQMAS with DQ sequence into 3D experiments.
- We obtain homonuclear correlation spectra with enhanced resolution.
- We demonstrate the experiments on 87Rb in RbNO3 and 11B in CsB3O5.
- Good signal to noise is obtained despite the long T1 of 11B in CsB3O5.
