Photoionisation and fragmentation of the stereoisomers of 4-t-butylcyclohexyl acetate and 4-t-butylcyclohexyl methyl ether

The fragmentation of the stereoisomers of 4-t-butylcyclohexyl acetate and 4-t-butylcyclohexyl methyl ether has been studied by photoionisation mass spectrometry at 1216 Å and 584 Å. Deuterium substitution and high resolution mass spectrometry have been used to gain further insight into the fragmentation pathways.
