Abstract
The mass spectra of stereoisomers of five 4-dimethylaminocyclohexanol derivatives were recorded under electron ionization, and fragmentation patterns were elucidated by exact mass measurements and metastable ion analysis.
The mass spectra showed differences in relative intensities of molecular ions between cis and trans isomers. The most characteristic feature of the mass spectral behavior of the compounds was fragmentation reaction, based on ionization of dimethylamino or hydroxyl groups.
