Using both optical-optical doubl resonance multiphoton ionization spectroscopy (OODR-MPI) and fluorescence excitation spectroscopy techniques,we have measured and assigned the single and double frequecy five-photon ionization spectrum as well as three-photon fluorescence excitation spectrum of iodine molecule,and identified a regular progression with a spacing of 72cm-1 as the excitation of the high vibrational level in the F0+u state. Based on the experimental results,we discussed the channel of excitation,emission and ionization of- iodine- molecule.
