We report on over 100 new bands of two vibronic types P u -S / g and P g -S / u in the A 1 P u -X 1 S / g laser induced fluorescence spectrum of C 3 in the wavelength range 386-463 nm. A fast electric discharge in the expansion region of a supersonic jet of CO produces rotationally cold but highly v

✦ Synopsis
The A 2 P-X 2 S (1,1) band of ZrN between 5642 and 5879 A ˚has been studied using laser induced fluorescence spectroscopy. ZrN was produced by reacting vaporized ZrCl 4 with microwave discharged N 2 gas. All the 12 branches expected from a 2 P-2 S transition have been observed and assigned. Various perturbations in the 2 P 3/2 substate £ Å 1 level have been found, in which the one at J Å 38.5 is ascribed to a degenerate state. The magnetic hyperfine structure of the 91 ZrN has also been identified. A least-squares fit up to J Å 30.5 yielded molecular constants for both the A 2 P and the X 2 S states of four isotopic molecules.
