ABSTRACT
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 1Σg+(0g+), A′3Πu(2u), A 3Πu(1u), and B 3Πu(0u+) electronic states as well as bands resulting from transitions to the repulsive regions of several I2 electronic states: the B′3Πu(0u-), B″1Πu(1u), 3Πg(2g), a 3Πg(1g), 3Πg(0g-), and C 3Σu+(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: 3Πg(0g-), 1Πg3(1g), 1 3Σg-3(0g+), and the 1Σg-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 3Πu(0u+) state.
