Optical heterodyne magnetic rotation enhanced velocity modulation spectroscopy was employed to observe thevisible absorption spectra of the B2∑ u+ -X2∑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. Arotational analysis was carried out to obtain molecular constants. With the Franck-Condon principle and the vibrationalBoltzmann distribution, we have estimated the vibrational temperature of C-2 to be about 3000K.
