By luminescence spectroscopy of the decomposition products during excitation by monochromatic electrons with various energies in the gas phase it was shown that the investigated electroactive molecules with approximately the same dimensions and different chemical structure have very different stability during interaction with electrons. Luminescence from hydrogen, С₂, and СН and also from СО, CN, I, Al, and Ir in molecules containing these elements or groups is observed in all the molecules. Luminescence from the decomposed molecules is observed at electron energies of ~40–50 eV (for the most typical components such as hydrogen in carbazole and metal in Al₂O₃). This indicates that the luminescence of the fragments results from their excitation by electrons. The amount and the luminescence intensity of the decomposition products increase with increase of temperature and electron energy.

通过气相中具有不同能量的单色电子激发期间分解产物的发光光谱表明，所研究的具有大致相同尺寸和不同化学结构的电活性分子在与电子相互作用期间具有非常不同的稳定性。在所有分子中都观察到含有这些元素或基团的分子中氢、С ₂和СН以及СО、CN、I、Al 和Ir 的发光。在约 40–50 eV 的电子能量下观察到分解分子的发光（对于最典型的成分，例如咔唑中的氢和 Al ₂ O _{3 中的}金属）。这表明碎片的发光是由电子激发引起的。分解产物的数量和发光强度随着温度和电子能量的增加而增加。
