Orientation help : Valine‐derived polyacetylenes are introduced as enantiomer‐differentiating alignment media. The F2‐coupled HSQC‐type NMR spectra of both enantiomers of isopinocampheol (IPC) display narrow line widths allowing for the precise extraction of residual dipolar couplings (black contour plot: (+)‐IPC in an isotropic phase, blue: (−)‐IPC in an anisotropic phase, and red: (+)‐IPC in an anisotropic phase; J =coupling constant).
