Photodissociation spectrum of cyanobenzene dimer cation. Absence of intermolecular resonance interaction Ohashi, Kazuhiko Ohashi Kazuhiko Nishiguchi, Masaharu Nishiguchi Masaharu Inokuchi, Yoshiya Inokuchi Yoshiya Sekiya, Hiroshi Sekiya Hiroshi Nishi, Nobuyuki Nishi Nobuyuki open access (c) VSP 1998 430 Electronic spectra of a homo-molecular dimer cation, (C6H5CN)2+, are measured by photodissociation spectroscopy in the gas phase. Broad features appeared in the 450–650 nm region are characteristic of π3 → πCN transitions of the C6H5CN+ chromophore. No intense band is observed in the 650–1300 nm region, where other aromatic dimer cations usually show charge resonance bands. Two component molecules of (C6H5CN)2+ cannot take a parallel sandwich configuration suitable for the resonance interaction, because of geometrical constraints due to other stronger interactions.
