AM1 and electron impact mass spectrometry study of the fragmentation of 4-acyl isochroman-1,3-diones

Abstract

Recently, in electron impact mass spectrometry (EIMS), it has been found a good correlation between the fragmentation processes of coumarins and the electronic charges of the atoms of their skeleton. In this paper, the same analytical method has been applied to 4-acyl isochroman-1,3-diones, whose mass spectra had been studied earlier and described for the very first time from our laboratory. Results obtained are in good agreement with the last study.DOI: http://dx.doi.org/10.4314/bcse.v26i2.15
