Abstract:

The mass spectra of the seven isomeric methylindoles were recorded and the metastable iondaughter ion ratios for the reactions me 130 to me 103 and me 103 to me 77 have been obtained. The ratios indicate that the decomposing M - 1 ions me 130 from the 4, 5, 6 and 7 isomers are energetically similar as are the M - 1 ions from the 2 and 3 isomers. The results observed for the me 103 to me 77 reaction showed that the decomposing me 103 ions from the 2, 3, 4, 5, 6 and 7 isomers all have the same energy distribution. N-Methylindole gave ratios which were similar to the 4 to 7 isomers at 70 eV but different at 20 eV. The ion kinetic energy IKE spectra of all the isomeric methlindoles were also obtained and the results compared with the data obtained from the metastable iondaughter ion approach. Author
