Ba. Rudenko et Iv. Maslov, Characteristic features of the gas-chromatographic retention of isomeric methylcyclohexene acids and their esters, J ANALYT CH, 55(1), 2000, pp. 37-39
Quantum-chemical calculations predicted that the diequatorial and diaxial c
onformations of transisomers of methylcyclohexene acids and their esters ar
e equally favorable. The characteristic features of the gas-chromatographic
retention of trans-2-methylcyclohexene3-carboxilic acid can be explained b
y the predominance of the diaxial conformation of this isomer under the con
ditions of the chromatographic experiment.
