✦ Synopsis

C, (A 'II,) produced from multi-photon dissociation of C,H, at 193 nm was probed via the Au = -2 sequence of the Freymark band system (E 'Xi + A 'II,) using laser induced fluorescence. The (u' = 0, U" = 2). (u' = 1, u" = 3) and a few lines of the (u' = 2, u" = 4) vibrational progressions were observed under nascent conditions. The intensity of the (u' -0, u" = 2) and (u' -1, u" = 3) bands are comparable but the (u' -2, u" -4) band is much weaker, implying that the vibrational population of the u" = 2 and 3 levels are approximately equal while that of U" = 4 is much smaller.

Laser-induced fluorescence excitation spectra of the A 'II,-X 'Z: electronic transition have been recorded in the laser wavelength range 386-463 nm using a novel source of rotationally cold but vibrationally excited C1. A large number of new transitions are observed and we report here on some promin
