Scaling the Alignment of Small Organic Molecules in Substituted Polyglutamates by Variable‐Angle Sample Spinning

Residual dipolar couplings provide important information for the stereochemical assignment of moieties in small organic molecules. By spinning the liquid-crystalline sample at an angle Θr to the magnetic field, the anisotropic interactions can be scaled to meet the experimental requirements. This is shown here for strychnine in the liquid-crystalline phases of poly(γ-benzyl-L-glutamate) and poly(γ-ethyl-L-glutamate) in CDCl3.
