Two new (2+1) multiphoton ionization spectra of gerade Rydberg states of molecular iodine are observed in the 310.0--322.5 and the 285.5--295.5 nm ranges. These spectra were obtained in both a conventional MPI cell and in a TOF molecular beam apparatus. A long progression in the 310.0--322.5 nm range is suggested to be 2/sub g/(/sup 2/Pi/sub 3/2//sub g/)ndsigma/sub g/, having a band origin at 62 440 cm/sup -1/. Three progressions in the 285.5--295.5 nm range are suggested to be 2/sub g/, 1/sub g/, 0/sub g/(/sup 2/Pi/sub 3/2//sub g/)(n+1)dsigma/sub g/, having band origins at 68 335, 68 407, and 68 434 cm/sup -1/, respectively. The photodissociation behavior of molecular iodine in a MPI process is discussed.
