## Abstract The diastereomeric differences (Δδ) were measured for a series of 11 (−)‐ω‐camphanic esters of secondary alcohols of known absolute configuration, using ^1^H NMR spectroscopy with Eu(fod)~3~ as shift reagent. This method is convenient and useful for the measurement of enantiomeric compo
