Spectroscopy Study Of Mass Spectra For Β -Lactams Mono , Dicarbonyl And Some Five Membered Ring

Abstract

AbstractThe mass fragmentation pattern of azetidine-2-one 3(c-e) and azetidne-2,3-dione 5f,5g in each casethe molecular ion peaks were observed corresponding to molecular weight of the coupled products.The base peaks were observed also for each compounds.the mass fragment
