3-coumarinyl carboxylates are 3-hydroxyl-coumarin derivatives obtained by O-acylated. In this work, we have studied thecorrelation between electronic charges of atoms and the fragmentation processes of these compounds.. The method has been successfully applied many times for EIMS, but only one time for ESI/MS. In this paper, we would like to apply the method to the ESI/MS spectra of another sery of 3-coumarinyl carboxylates. Good correlations was obtained.
