RELAYED ANISOTROPY CORRELATION NMR - DETERMINATION OF DIHEDRAL ANGLES IN SOLIDS

摘要

A two-dimensional solid-state NMR method is proposed for determining the mutual orientation of the two interaction tensors in each of which a different chemical group participates, from which information on the dihedral angle can be the C-13(1) chemical shift anisotropy and the C-13(2)-H-1 dipolar coupling via polarization transfer. The O-C-1-C-2-H dihedral angle as well as the orientation of the C-13(1) chemical shift tensor were determined from the spectrum. [References: 31]
