Abstract

Electronic spectra of a homo-molecular but inequivalent dimer ion, (C₆H₅OH)⁺₂, are measured by photodissociation spectroscopy. A broad band appeared in the 340-440 nm region is characteristic of the C ← X transition of a phenol ion chromophore, suggesting that the dimer ion consists of a phenol ion and a neutral phenol. No strong band is observed in the 450-1400 nm region, whereas other aromatic dimer ions usually show charge resonance bands in near-infrared region. Owing to the geometrical constraint of an O-H ⋯ O hydrogen bond in (C₆H₅OH)⁺₂, the two aromatic rings cannot be in a parallel configuration suitable for the resonance interaction.
