説明
The characterization and metastable decomposition of isobaric ions from several compounds are described by using high-resolution mass spectrometry (HR-MS) and mass-analyzed ion kinetic energy (MIKE) spectrometry. The m/z 45 ions from 2-methoxyethylamine, CH3OCH2CH2NH2 (1) consists of two isobaric ions, methoxymethyl ion, CH3OCH2+, and C2H7N+ ion. The former decomposes into the m/z 29 ion by losing CH4 in metastable time window. Although the latter decomposes into the m/z 30 and 18 ions, its structure could not be confirmed in this study. The m/z 69 ions generated from methyl trifluoroacetoacetate, CF3COCH2COOCH3 (2) and 1,1,1,5,5,5-hexafluoro-2,4-pentanedione, CF3COCH2COCF3 (3) also consists of two isobaric ions, trifluoromethyl ion, CF3+, and protonated carbon suboxide, OCCHCO+. The former does not decompose into any ions in the metastable time window. On the other hand, the latter decomposes into m/z 41 ion by losing CO.
