Characterization of hydrogenated derivatives of methyl- and dimethyldicyclopentadiene isomers by gas chromatography–mass spectrometry and carbon-13 nuclear magnetic resonance spectroscopy

Résumé

The identification of the di- and tetrahydrogenated derivatives of methyl- and dimethyldicyclopentadiene isomers has been performed directly in the hydrogenated mixtures, by comparing the results from the gas chromatography–mass spectrometric mass balance with those from quantitative 13C nuclear magnetic resonance spectra. The assignment of the carbons of these isomers has been realized by analysing data from J-modulated spin-echo sequences and by applying semi-empirical rules for the influence of the methyl groups on the carbon chemical shifts in cyclopentane and norbornane ring systems.
