Abstract

Electron donors such as diethyl ether, benzene, and electron accepters such as halogens combine to form charge transfer (C-T) complexes, A C-T complex gives a unique absorption band generally in the UV-visible region, which is not present in the spectrum of the donor or the acceptor, A new approach to study a C-T complex is to isolate the complex in the gaseous state and find its occupied orbital energies from UV photoelectron spectroscopy (UVPES), excited states from electron energy loss spectroscopy (EELS) and compare the orbital energies from ab-initio molecular orbitals (MO) calculations, Combined use of UVPES, EELS and MO calculations provides a complete molecular description of a C-T complex, Bonding,and antibonding orbitals responsible for hv(C-T) absorption in a C-T complex can be identified, In this article we describe this new approach to study C-T complexes.
