IKE and metastable ion evidence for fragmentation pathways in the mass spectra of organolead substituted nitrogen heterocycles

Autor: Robert E. Sacher, M.L. Bazinet, Charles Merritt

Publikováno v: International Journal of Mass Spectrometry and Ion Physics. 17:9-16

Spectra—structure correlations are made of methylplumbyl substituted heterocyclic compounds consisting of nitrogen containing condensed five and six membered rings. Fragmentation behavior under electron impact is elucidated by means of IKE and meta
