## Abstract From a 300 MHz spectral study of mono‐to trisubstituted cyclohexanes, allowing a re‐examination of some of their ^1^H NMR spectral parameters, it is shown that it is possible to predict with reasonable accuracy the shifts (in CCl~4~) of the ring protons. A substantial feature in this is
