研究了由气态 NO2/N2O4 冷凝而成的固体 N2O4 的拉曼光谱。当在 80 K 下沉积时,形成 O2NNO2 二聚体。 15 K 下的沉积会额外产生 NO2 单体和 O2NONO 异构体的条带。升温至 180 K 会诱导自电离生成 NO+NO−3,NO+NO−3 在 15–180 K 范围内保持稳定。这种转变可能是通过二聚体的低能晶格模式或ν4扭曲振动引起的分子间过程。
Raman spectra of solid N2O4 condensed from gaseous NO2/N2O4 were investigated. When deposited at 80 K the O2NNO2 dimer is formed. Deposition at 15 K produces additionally bands of the NO2 monomer and the O2NONO isomers. Warming to 180 K induces autoionization to NO+NO−3 which remains stable over the 15–180 K range. The transition is probably an intermolecular process invoked through the low energy lattice modes or ν4 twist vibration of the dimer.
