Irradiation of the pure title compounds and a range of dilute solid solutions produces a range of matrix-isolated radicals, identified by their EPR spectra. These include electron-loss centres, HNCN and (Me2NCN)+, and electron capture centres HNC(H)N˙– and Me2N˙. The former is a tautomer of the parent anion and the latter is formed by loss of CN–. In aqueous alkali glasses, the radical anion ˙N2CO3– is thought to be formed by addition of O˙– to CN2–2.
对纯标题化合物和一系列稀释固体溶液进行辐照,会产生一系列基质分离的自由基,可通过它们的EPR光谱进行识别。这些自由基包括电子损失中心HNCN和(Me2NCN)+,以及电子捕获中心HNC(H)N˙–和Me2N˙。前者是母体阴离子的互变异构体,后者是通过失去CN–形成的。在水基碱玻璃中,自由基阴离子˙N2CO3–被认为是通过O˙–与CN2–2加成形成的。
