## Abstract A LIS analysis of 2‐isopropyl‐1,3‐dioxane (1) and 2‐methyl‐2‐phenyl‐1,3‐dioxane (2) is reported. The monodentate complexing model gives good agreement with the observed shifts in both compounds, whereas the bidentate model (lanthanum binding to both oxygens) does not give an acceptable

A LIS investigation of analogues of amiodarone containing the 3-benzoyl-2-butylbenzofuran system has been performed, utilizing the pseudo-contact shifts of all the proton and carbon nuclei in the molecules. The 13C diamagnetic shifts were removed by use of La(fod), and the pseudo-contact shifts were
The complete assignment of the proton chemical shifts for kxo-norborneol was obtained from a COSY experiment at 250 MHz. Using these assignments the conformation of this molecule in solution was studied using the lanthanide-induced shift technique, applying a new three-site lanthanide complexation m
