NMR Crystallography:Disentangling Crystallographic Inequivalence and Crystallographic Forms of L-Arginine by One- and Two-Dimensional Solid-State NMR Spectroscopy

Printer-friendly version

Solid-state NMR can often supplement information obtained from diffraction crystallography.

Résumé: 

Overlapping 13C or 15N solid-state NMR spectra from crystallographically different forms of L-arginine hydrochloride can be separated by exploiting differential proton T1 relaxation in conjunction with cross polarization.
