H-2 solid state NMR spectra of a polypeptide in an oriented membrane e
nvironment is demonstrated to have an orientational resolution of 0.3
degrees. Such data results in high resolution structural constraints.
Similar spectra are demonstrated at 23.2 T using a resistive magnet at
the National High Magentic Field Laboratory. (C) 1997 Elsevier Scienc
