Abstract The emission spectra of C2 Swan bands transition were observed in 430-600 nm region by Q-switched laser ablation target of Al reacting with CF4，CCl4 and CH2Br2 beams. Five vibration band sequences (Δｖ=2，1，0，-1 and -2) of d3Πｇ-a3Πｇ were identified and the largest vibration number of excited state d is 6. Using a local thermal equilibrium model, the vibrational temperature of d state was determined to be about 6 000 K. Meanwhile, some bumps, separated by about 0.3 nm, were observed between vibrational bands of Δｖ=0 and -1 sequences, which were due to accidental and periodical accumulations of rotational lines belonging to several vibrational bands. The formation mechanism of excited C2 ｄ3Πｇ state is considered as when laser induced Al plasma expansion in the background reaction gas sample, the collisions between metal particles and gas sample molecules cause the dissociation of precursors, so atomic C is produced. Meanwhile, the shock wave induced by plasma expansion might cause molecules dissociation as well. Then C atoms combine to form C2 in the ground state X1Σ＋ｇ(Te=0 cm-1) or first excited state ａ3Πｕ(Te=716 cm-1). The electronic energy transfer between excited state Al (2S1/2)(Te=25 348 cm-1) and C2 ａ3Πｕ state produces the excited state ｄ3Πｇ(Te=20 022 cm-1). Another mechanism that may be possible is that ｂ3Σ-ｇ state of C2 is produced first, then undergoes a radiationless transition into ｄ3Πｇ state through crossing with the ｄ3Πｇ,ｖ′＝6 level. But the vibrational population of ｖ′＜6 levels is formed by collision relaxation.
