Substantial resolution and sensitivity enhancements of solid-state 1 H detected 14 N HMQC NMR spectra at very fast MAS rates up to 80kHz, in a 1mm MAS rotor, are presented. Very fast MAS enhances the 1 H transverse relaxation time and efficiently decouples the 1 H- 14 N interactions, both effects leading to resolution enhancement. The micro-coil contributes to the sensitivity increase via strong 14 N rf fields and high sensitivity per unit volume. 1 H- 14 N HMQC 2D spectra of glycine and glycyl-l-alanine at 70kHz MAS at 11.7T are observed in a few minutes with a sample volume of 0.8μL.
