Characteristic features of the gas-chromatographic retention of isomeric methylcyclohexene acids and their esters

Quantum-chemical calculations predicted that the diequatorial and diaxial conformations oftrans-isomers of methylcyclohexene acids and their esters are equally favorable. The characteristic features of the gas-chromatographic retention oftrans-2-methylcyclohexene-3-carboxilic acid can be explained by the pre-dominance of the diaxial conformation of this isomer under the conditions of the Chromatographic experiment
