The Photodissociation dynamics of CO2 has been reinvestigated using the photofragment translational spectroscopic technique based on direct vacuum ultraviolet (VUV) ionization using synchrotron radiation. The product translational energy spectrum as well as the product angular anisotropy have been measured for both the CO and O products. The experimental results indicate that the O(P-3) + CO channel has an anisotropy parameter of 1.25, while that for the O(D-1) + CO channel depends on the translational energy dependent.
