Abstract: | To test the similarity of chemical ionization (CI) spectra of esters to the collision-induced decomposition mass-analyzed ion kinetic energy (CID-MIKE) spectra of protonated esters, the CID-MIKE spectra of the M + 1]+ ions of nineteen aliphatic esters were studied. The major fragments produced in the two kinds of experiment are similar, but there are significant differences in the ions of high mass, which would reduce the usefulness of library searches of CI spectra to identify MIKE spectra of M + 1]+ ions. |
