The two-photon resonant transitions of high electronic state (E) of IBr molecule have been observe using the technique of the multiphoton ionization spectra. Aooording to the vibrational spectra of IBr with the Franok-Condon principle, we have obtained for the first time the rotational constant Be of state (E) of IBr, which is (0.0653±0.0003)cm-1.
