Vacuum ultraviolet fluorescence of iodine has been used to detect excitations through the $73384cm-1$ to $60150cm-1$ energy range. Eleven vibrational progressions corresponding to gerade Rydberg states of molecular lodine are identified. Twenty-two atomic LIF transitions following photodissociation are also identified. Combining and comparing these results with multiphoton ionization $data1$ provides a better characterization of the gerade Rydberg sates and new insight into the predissocaition and photodissociation processes of the iodine molecule.
