Abstract

The slow exchange 360 MHz ^1^H NMR spectra of cis‐transoid‐cis‐perhydroanthracene and of cis‐decalin have been assigned. Shift increments due to the cis‐annelation of a tetramethylene bridge to cyclohexane are presented.

## 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
