The use of the biphasic isotropic/nematic region in a bisperylene imide‐based lyotropic liquid crystal system allows the extraction of proton‐carbon 1DCH residual dipolar couplings in aqueous solution from a single F1‐coupled HSQC experiment. The method was successfully applied to the RDC‐based conformational analysis of sucrose. [ABSTRACT FROM AUTHOR]

Chemically cross-linked polyacrylontrile polymer gels, have been prepared as an alignment medium compatible with DMSO-d 6 . These gels allow measurement of residual dipolar couplings (RDCs) and residual chemical shift anisotropies (RCSAs) with good accuracy as tested with brucine and α-santonin natural compounds. The gels can be reversibly compressed allowing easy measurement of RCSAs. They also present good physical homogeneity, clean HSQC spectra with little background 1 H signals, and allow unambiguous referencing of 13 C spectra for RCSA extraction., (Copyright © 2019 Elsevier Inc.
