Photoelectron spectroscopy charge transfer

The thiiren 1,1-dioxide system has been investigated theoretically and by u.v. photoelectron spectroscopy. Charge transfer from the carbon-carbon double bond to the SO.2 unit is about one-third that predicted for the cyclopropenone system. Aromaticity decreases in the order cyclopropenone > tropone >...

T. Waters, X.-B. Wang and L.-S. Wang, Coord. Chem. Rev., 2007, 251, 474. Review describing the use of electrospray to transfer negatively charged transition metal complexes to the gas phase for photoelectron spectroscopy. Examples discussed include square planar and octahedral halide complexes, metal-metal bonded species, transition metal bis(diihiolene) complexes, and mononuclear and polynuclear iron-sulfur clusters.
