Abstract
The problem of the utilization of a series of mass-spectrometric experimental data [the stabilities with respect to electron impact, the ratios of the intensities of the peaks of the ions responsible for the observed tautomerism, the first ionization potentials (FIP), the appearance potentials (AP), and the ΔE values] to distinguish the tautomeric forms in the azides and tetrazoles of pyrimido-as-triazines is discussed.
