摘要
A method for the measurement of residual chemical shift anisotropy in one experiment using a biphasic isotropic/ anisotropic lyotropic liquid crystalline medium based on poly-gamma-benzyl-L-glutamate as the alignment medium is presented. This approach is demonstrated on the model compound strychnine and neotricone, a depsidone natural product with a questionable structural assignment based on comparison with the closely related excelsione and in-depth density functional theory calculations.
