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.
