Indirect high-resolution detection for quadrupolar spin-3/2 nuclei in dipolar HMQC solid-state NMR experiments

► New sequence: First 2D HMQC with isotropic resolution on spin-3/2 nuclei. ► High efficiency and higher S/N than a regular HMQC. ► Theoretical description: optimal pulse length and excitation time prediction. ► Fairly easy to setup sequence: few pulses to optimize. ► Should allow insensitive nuclei detection with high resolution.
