A moderately concentrated solution of a helically chiral polyisonitrile forms a stable two‐phase system in CDCl 3 with the dense phase being close to isotropic and the less dense layer forming a completely anisotropic lyotropic liquid crystalline phase. This enables the enantiodifferentiating measurement of isotropic and anisotropic NMR parameters from a single sample by novel spatially resolved NMR methods.
