Assessment of various electronic structure methods for characterizing temporary anion states: application to the ground state anions of N2, C2H2, C2H4, and C6H6.

The theoretical characterization of temporary anions is an especially challenging problem. In the present study we assess the performance of several electronic structure methods when used in conjunction with the stabilization method to characterize temporary anion states. The ground state anions of N2, C2H2, C2H4, and C6H6 are used as the test systems, with the most extensive testing being done for N2.
