Perspectives in the application of residual dipolar couplings in the structure elucidation of weakly aligned small molecules

Abstract: This perspective article aims to review the general methodology in the application of residual dipolar couplings (RDCs) in the structure elucidation of small molecules and give the author's view on challenges for future applications. Recent improvements in the availability of alignment media, new pulse sequences for the measurement of couplings and improvements in the analysis software have garnered widespread interest in the technique. However, further generalization is needed in order to make RDC analysis in… Show more

“…To overcome these problems, new methods based on anisotropic NMR parameters have been introduced . Anisotropic NMR‐based parameters are sensitive reporters of the global orientation of molecular bonds and chemical shielding tensors and provide a robust means for the structure assignment/validation of complex organic molecules . Access to anisotropy‐based NMR parameters requires the generation of anisotropic environments in solution through the use of dedicated alignment media .…”

Access to anisotropy‐based NMR parameters requires the generation of anisotropic environments in solution through the use of dedicated alignment media . Despite intensive research, the connection between the structure of an alignment medium, the atomic structure of small molecules, and molecule‐specific anisotropy‐based NMR parameters has remained enigmatic.…”
