摘要
在CCl_4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CCl_2自由基→跃迁。近400条谱带归属为^(35)Cl-C-^(55)Cl和^(35)Cl-C-^(37)Cl的(v_1~′,v_2~′,0)→(v_1^(″),v_2^(″),0)一系列前进带组,并排列成Deslandres表。光谱分析给出CCl_2在激发态和基态的v_1和v_2振动频率及同位素位移,其中气相CCl_2在基态的数据尚未见文献报道。
In DC discharge of CC14 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 (v'1,v'2, 0) →(v'1,v'2, 0) progressions of 35C1-C-35C1 and 35C1-C-37C1, 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.
