[Phenol⋅CO]+ was studied using a combination of two-color resonant zero kinetic energy (ZEKE) spectroscopy and mass analyzed threshold ionization (MATI) spectroscopy to investigate the interaction of the CO ligand with a hydrogen-bonding cation. Vibrational progressions were observed in three intermolecular modes, the in-plane bend (42 cm−1), stretch (130 cm−1), and in-plane wag (160 cm−1), and are consistent with a planar hydrogen-bonded structure where the CO bonds through the carbon atom to the phenol OH group. Dissociation energies for the S0, S1, and D0 states were determined as 659±20, 849±20, and 2425±10 cm−1, respectively. The cationic and neutral dissociation energies of the phenol⋅CO complex are considerably stronger than those of phenol⋅N2, demonstrating the extent to which the larger quadrupole of CO affects the strength of binding. © 1999 American Institute of Physics.
