N2 - We report the anion photoelectron spectrum of I2- taken at 5.826 eV detachment energy using velocity mapped imaging. The photoelectron spectrum exhibits bands resulting from transitions to the bound regions of the X g+1 (0g+), A′ Π u 3 (2u), A Π u 3 (1u), and B Πu3 (0u+) electronic states as well as bands resulting from transitions to the repulsive regions of several I2 electronic states: the B′ Πu3 (0u-), B″ Πu1 (1u), Πg3 (2g), a Πg3 (1g), Πg3 (0g-), and C u+3 (1u) states. We simulate the photoelectron spectrum using literature parameters for the I2- and I2 ground and excited states. The photoelectron spectrum includes bands resulting from transitions to several high-lying excited states of I2 that have not been seen experimentally: Πg3 (0g-), Πg1 3 (1g), 1 g-3 3 (0g+), and the g-1 3 (0u-) states of I2. Finally, the photoelectron spectrum at 5.826 eV allows for the correction of a previous misassignment for the vertical detachment energy of the I2 B Πu3 (0u+) state.
