What is Proton Magnetic Resonance Study of Rotational Isomerism in Vinylcycloalkanes about?
## Abstract The vicinal coupling constant, __J__(12), between the vinyl CH and the ring CH protons in vinylcyclohexane was calculated from a ‘partial molecule’ six‐spin system. The 100 and 270 MHz results are in good agreement; those at 60 MHz were, however, still inaccurate in this approximation. __J__(12) increases with increasing solvent polarity and decreasing temperature. The energy difference between the s‐__trans__ and __gauche__ conformers in both C~2~Cl~4~ and perdeuterioacetone solvents is 879 ± 167 __J__ mol^−1^ (210±40 cal mole^−1^). The s‐__trans__ conformer is the most stable, in contrast to the isoelectronic cyclohexylcarboxyaldehyde where the __gauche__ rotamers are lower in energy.
