Study of hot bands in the B 2 Σ + u -X 2 Σ + g system of C - 2 anion
2003
Optical heterodyne magnetic rotation enhanced velocity modulation spectroscopy was employed to observe the visible absorption spectra of the B2Σ+u-X2Σ+g electronic transition of C-2. Four hot bands (0,1), (1,2), (2,3) and (3,4) have been observed and the band (3,4) is measured directly for the first time, so far as we know, by absorption. A rotational analysis was carried out to obtain molecular constants. With the Franck-Condon principle and the vibrational Boltzmann distribution, we have estimated the vibrational temperature of C-2 to be about 3000K.
