Infrared photodissociation spectra of the aniline ion solvated by water and methanol molecules are measured in the 2600-3800 cm-1 region. Substantially red-shifted and broadened transitions are distinctly observed at 3105 and 2915 cm-1 for aniline+-(H2O)1 and aniline+-(CH3OH)1, respectively, and assigned to the stretching vibration of the hydrogen-bonded NH oscillator of the aniline+ moiety. The spectra of aniline+-(H2O)2 and aniline+-(CH3OH)2 demonstrate a large perturbation to both of the NH oscillators, indicating that each NH bond is bound to a solvent molecule in the most stable structure.
