title: Ab initio study of temporary anions of benzene and fluorobenzenes using the multipartitioning many-body perturbation theory.
abstract: We present an ab initio study of the lowest states of five temporary anions: C6H6(-), C6H5F(-), 1,4-C6H4F2(-), 1,2,3-C6H3F3(-), and 1,3,5-C6H3F3(-). Vertical positions and widths of anionic resonances have been calculated within the stabilization graph approach using the multipartitioning form of the many-body perturbation theory for state-selective effective Hamiltonians restricted to second order (MPPT-R). Good agreement with experimentally derived estimates justifies application of the MPPT-R method for theoretical investigation of haloaromatic temporary anion radicals.
