Abstract:
We report the anion photoelectron spectrum of I2− taken at 5.826eV detachment energy using velocity mapped imaging. The photoelectron spectrum exhibits bands resulting from transitions to the bound regions of the XΣg+1(0g+), A′Πu3(2u), AΠu3(1u), and BΠu3(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), aΠg3(1g), Πg3(0g−), and CΣu+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−), Πg13(1g), 1Σg−33(0g+), and the Σg−13(0u−) states of I2. Finally, the photoelectron spectrum at 5.826eV allows for the correction of a previous misassignment for the vertical detachment energy of the I2 BΠu3(0u+) state.
