Electron-Benzene and Benzene-Benzene Potentials for Simulation of an Excess Electron in Liquid Benzene

Empirical potentials are proposed to simulate benzene and an excess electron in liquid benzene. The benzene-benzene potential is closely modelled on another that has previously been well tested in the condensed phase. We have improved the electrostatic model of benzene, and to be consistent we have used the same representation for both potentials. The electron-benzene potential is derived in part using ideas from density functional theory, and the principles could equally well be applied to other electron-molecule systems. The electron is found to be repelled from the benzene, except in a few regions of space, mainly close to the molecular plane.
