用紫外光电子能谱研究了M+N2O和M+O3气相反应的产物，其中M=Na或K，并借助从头算分子轨道计算的结果分配了谱带。对于M+N2O反应，观察到的产物是MO+N2。测量与金属一氧化碳MO相关的光电子带可以测定NaO和KO的第一绝热电离能。所得结果为AIE[NaO（X 2Π）]=(7.1±0.1)eV, AIE[KO（X 2Π）]=(6.9±0.1)eV。对Li+N2O反应的类似研究得出AIE[LiO（X 2Π）]=(7.6±0.2)eV。在M=Na或K条件下，M+O3反应生成MO+O2为主要产物。然而，对于每个反应，观察到一个波段被分配给二级反应产物MO2的第一电离能。NaO2和KO2的第一绝热电离能分别为AIE[NaO2(X 2A2)]=(6.2±0.2)eV和AIE[KO2(X 2A2)]=(5.7±0.1)eV。对于M+…
Products of the gas‐phase reactions M+N2O and M+O3, where M=Na or K, have been investigated with UV photoelectron spectroscopy and bands have been assigned with the assistance of results from ab initio molecular orbital calculations. For the M+N2O reactions, the observed products were MO+N2. Measurement of the photoelectron bands associated with the metal monoxide MO allowed determination of the first adiabatic ionization energies of NaO and KO. The values obtained were AIE[NaO(X 2Π)]=(7.1±0.1) eV and AIE[KO(X 2Π)]=(6.9±0.1) eV. A similar study of the Li+N2O reaction gave AIE[LiO(X 2Π)]=(7.6±0.2) eV. The reactions M+O3, with M=Na or K, were observed to give MO+O2 as the major reaction products. However, for each reaction, a band was observed which was assigned to the first ionization energy of the secondary reaction product MO2. From the spectra obtained, the first adiabatic ionization energies of NaO2 and KO2 were measured as AIE[NaO2(X 2A2)]=(6.2±0.2) eV and AIE[KO2(X 2A2)]=(5.7±0.1) eV. For both the M+...
