Fast‐atom bombardment (FAB) and Electrospray ionization (ESI) mass spectra of meso‐pyrazolylporphyrins have been studied. Both types of spectra allow one to determine the molecular weight of each compound studied. ESI mass Spectra show two further nteresting properties. First, there is addition of only one and two protons. Second, the ESI spectra show cluster ions for which the measured and theoretical isotope rations are in good occurrence of reduction phenomena prevents such a calculation from the FAB mass Spectra.
