Dispersed fluorescence observations of the CO/A 1Pi to X 1Sigma+/ transitions from photodissociation of CO2

The spectra of vacuum ultraviolet (vuv) fluorescence resulting from the excitation of CO2 by photons from an intense line emission source at 15 wavelengths in the range 449-955 A were obtained. The vibrational population distributions for the v = 0, 1, and 2 levels of the CO(A 1Pi) fragments were obtained at several incident photon wavelengths from 700 to 923 A. At incident photon wavelengths of 901 and 923, the relative intensities of the CO(A to X) bands were determined, permitting examination of the variation of the electronic transition moment with the r centroid.
