| 摘 要： | 在CCl4蒸汽的直流放电中,观测了从520到630nm波长范围的荧光发射并确认为CCl2自由基A→X跃迁。近400条谱带归属为35Cl-C-35Cl和35Cl-C-37Cl的(v1′,v2′,0)→(v1″,v2″,0)一系列前进带组,并排列成Deslandres表。光谱分析给出CCl2在激发态和基态的v1和v2振动频率及同位素位移,其中气相CCl2在基态的数据尚未见文献报道。

| Abstract: | In DC discharge of CCl2 vapor, the emission spectrum from 520 to 630 nm has been observed and identified as the A→X transition of CC12 radical. About 400 bands were assigned to (v1′,v2′,0)→(v1″,v2″,0) progressions of 35Cl-C-35Cl and 35Cl-C-37Cl, and tabulated to Deslandres tables. Spectral analysis gave out the vibrational frequencies v1, v2 and their isotopic shifts in which the data of gas-phase CCl2 in ground state were not found yet in literatures. |
