Mass Spectrometry of Nucleic Acid Constituents. Electron Ionization Spectra of Selectively Labeled Adenines

Article abstract of DOI:10.1021/ja00376a017

The unimolecular decomposition of adenine following electron ionization has been studied on the basis of extensive isotopic substitution to establish the extent of site selectivity in fragment ion formation.Carbon-13 labeling at C-2, with earlier publishe
