Lanthanide tetrakis(/l-diketonate) anions are effective NMR shift reagents for organic salts. The shifts in the 'H NMR spectra were analyzed and explained without invoking a contact shift mechanism.

## Abstract The potential use of sodium anthraquinone 2‐sulphonate (ASANA) as a general‐purpose shift reagent for cyclodextrins is reported. It is demonstrated that completely resolved proton NMR spectra are obtained on inclusion of the host in the cavity of β‐and y‐cyclodextrins. The inclusion com
