## Abstract The conformational equilibrium constants for a series of 1‐alkyl substituted cyclohexanols have been determined using a lanthanide shift reagent, and the results compared with other methods. In comparison to other technique greater preference is shown by the hydroxyl group for the equat

The complete assignment of the proton NMR spectra of several a-, pand ynaphthoflavones at 100 MHz using Eu(fod), and double resonance experiments has been carried out. The compounds were found to associate at the carbonyi oxygen, by analogy with flavones where complete structural assignment can be a
