"The infrared spectra of the O2- benzene and O4- benzene complexes are determined by means of Ar predissociation spectroscopy. Several transitions due to CH stretch fundamentals and various combination bands are observed in the 2700-3100 cm-1 region. The experimental results are interpreted with the aid of electronic structure calculations. A comparison of the calculated and experimental spectra reveals that the spectrum of O2- benzene most likely arises from an isomer where the superoxide molecule binds preferentially to one CH group of benzene. In contrast, the spectrum of O4- benzene yields a CH pattern remarkably similar to that displayed by the C2 X- benzene (X=halogen) complexes, consistent with a structure with two CH groups equally involved in the bonding. The lower energy vibrational fundamental transitions of the O4- anion are recovered with a slight redshift in the O4- benzene spectrum, establishing that this charge-delocalized dimer ion retains its identity upon complexation. © 2007 American Institute of Physics."^^ .
