Abstract
The chemical ionization mass spectra of the isomeric 2,4βadamantanediol diacetates and dimethyl ethers have been determined using methane and isobutane as reagent gases. The significant differences in the spectra of the diacetates allow an unambiguous identification of the isomers. The spectra of the trideuteroacetates reveal the occurrence of protolysis in the ionizing plasma.
