IKE Spectra of Stereoisomers of Some Monoterpenes

Abstract

Ion kinetic energy spectroscopy(IKES)provides new and useful information on the structure of ions formed by mass spectrometer. This method was applied to the distinc tion of isomeric monoterpene pairs whose mass spectra are nearly identical. It is shown that the IKE spectra can be used for such isomers, which was exemplified by the case of borneol and iso-borneol.
