title: Disentangling crystallographic inequivalence and crystallographic forms of L-arginine by one- and two-dimensional solid-state NMR spectroscopy.
abstract: Overlapping (13)C or (15)N solid-state NMR spectra from crystallographically different forms of L-arginine hydrochloride can be separated by exploiting differential proton T(1) relaxation in conjunction with cross-polarization. Dipolar (13)C-(13)C and (15)N-(15)N two-dimensional correlation experiments reveal resonances belonging to crystallographically and magnetically inequivalent molecules.
