用激光诱导荧光光谱法在室温下观察到C2阴离子在B 2 u+-X2 g+体系的（2，4），（3，5）和（4，6）带的多普勒限制激发光谱.在光谱中分辨出了预期的2 π-2 π跃迁转动线的双峰。实验测定了X2 π g+态v= 4-6能级的振动项值和分子常数。
Doppler-limited excitation spectra of the C 2 anion were observed for the (2, 4),(3, 5), and (4, 6) bands of the B 2 Σ u+–X 2 Σ g+ system by laser-induced fluorescence spectroscopy at room temperature. Doublet peaks which are expected for rotational lines of a 2 Σ–2 Σ transition were resolved in the spectra. The vibrational term values and molecular constants of the v= 4–6 levels in the X 2 Σ g+ state were experimentally determined.
