Abstract

Infrared photodissociation spectra of (benzene-water-Ar)+ in the 3 μm region were observed by monitoring benzene+ and (benzene-water)+ fragments. The spectral features showed that the Ar atom locates on the benzene ring, preserving the same structure as that of (benzene-water)+, in which the water moiety is bound to the side of benzene+ by the charge-dipole interaction and C-H⋯O hydrogen bonds. We evaluated the binding energy of (benzene-water)+ to be D0 = 3290 ± 120 cm-1 by analyzing the appearance energy dependence of the fragments. The binding energy of the cluster cation gave us the adiabatic ionization potential of the neutral (benzene-water) cluster, IP0 = 72160 ± 150 cm-1.
