Notes:
The mass spectrometric fragmentation of the five cis-trans isomeric 1,2,4,5-tetramethylcyclohexanes is influenced by their configuration. The thermochemically stable isomers show a higher abundance of the [M—CH3]+ ions and a lower abundance of the [M—C2H5]+ ions than the strained isomers. The [M—CH3]+/[M—C2H5]+ intensity ratio correlates with the enthalpy difference ΔHisom and with the mean number of gauche arrangements ZgI of the stereoisomers.
