## Abstract The conformational equilibrium constants for isomeric methylcyclohexanols (__cis__‐ and __trans__‐1,2‐, 1,3‐ and 1,4‐methylcyclohexanols) have been determined from peak area measurements in the completely proton decoupled low temperature ^13^C NMR spectra of the individual conformers. T

## Abstract The preferred conformation of 8‐methyl‐__cis__‐thiahydrindane has been both estimated by ^13^C NMR chemical shifts and determined by low temperature ^13^C NMR spectroscopy to be the conformer with the methyl group equatorial with respect to the cyclohexane ring. This result is in disagr
## Abstract The ^13^C and ^1^H NMR spectra of a series of methiodides of mono‐ and di‐C‐methyl derivatives of 1‐methyl‐4‐phenyl‐4‐piperidinols are reported and chemical shift data analysed in terms of configurations and conformations of isomeric sets. Results demondtrate the value of quaternary sal
