Abstract

Partial alignment of molecules in polar organic solvents for the measurement of residual dipolar couplings (RDCs) in high-resolution NMR spectroscopy can be achieved by stretched poly(vinyl acetate) gels. The method opens the door of RDC-derived structural information (e.g. from DCH couplings, see picture) to new classes of molecules by closing the existing gap between apolar and aqueous solutions. (Figure Presented).
