Abstract
| - The o-cyanophenol molecule and its hydrogen-bonded complexes with one and two molecules of water andmethanol have been investigated by laser-induced fluorescence excitation, dispersed emission, and IR/UVdouble-resonance spectroscopy combined with DFT calculations. The sole conformer observed in the jet hasa cis geometry due to the stabilizing interaction between the OH and CN substituents. The shifts of theelectronic transition and the modification of the OH ground-state frequencies together with the calculatedgeometry point to a cyclic structure of the complexes. In the 1:1 complexes, the solvent OH binds as a protonacceptor to the phenol OH and as a proton donor to the CN group. The 1:2 complexes involve in a similarway the insertion of the solvent dimer (water)2 or (methanol)2 between the OH and CN substituents of themolecule.
