✦ Synopsis

The positiveion fast atom bombardment (FAB) mass spectra of eserine and some carbamate analogues were recorded and showed a partially different fragmentation process, with respect to that of the corresponding chemical ionization (CI) fragmentation. This unexpected behaviour could be explained by taking into account the known solution chemical behaviour of the protonated species, and assigning to the molecular species observed under FAB a different-yet related-molecular connectivity. This may be considered as evidence that the sputtered species under FAB closely reflect the chemical behaviour of the analysed molecule in the solution environment.
