Rapid Natural‐Abundance 2D ¹³C–¹³C Correlation Spectroscopy Using Dynamic Nuclear Polarization Enhanced Solid‐State NMR and Matrix‐Free Sample Preparation

Abstract

Ultra-fast: Substantial solid-state NMR sensitivity can be achieved using dynamic nuclear polarization and matrix-free sample preparation (that is, absence of solvent and cryoprotectant). This method avoids line-broadening, maximizes sample filling factor, and allows natural-abundance 2D 13C–13C dipolar correlation experiments to be carried out in tens of minutes. MW=microwaves.
