观察了一系列芳基重氮阳离子的电喷雾（ES）质谱并观察到完整的离子。碰撞激活的分解导致氮的轻易损失，形成相应的芳基阳离子。比较恒定碰撞能量下每种阳离子的完整离子和碎片离子的比例，得出重氮阳离子的相对稳定性顺序，这与通过化学方法在溶液中测定的相似。观察了相应重氮化物的完整离子的负离子 ES 质谱。与重氮阳离子一样，它们也很容易在碰撞活化分解中失去氮，得到酚阴离子 [OAr]−。
Electrospray (ES) mass spectra were observed for a series of aryldiazonium cations and the intact ions were observed. Collisionally activated decompositions lead to facile loss of nitrogen to form the corresponding aryl cations. Comparisons of the proportion of intact and fragment ions for each cation at a constant collisional energy lead to an order of relative stability for the diazonium cations which is similar to that determined in solution by chemical methods. Negative-ion ES mass spectra were observed for the intact ions for the corresponding diazotates. Like the diazonium cations, they also readily lose nitrogen in collisionally activated decompositions to give the phenolate anions [OAr]−.
