Infrared photodissociation spectroscopy of aniline(+)-(water)(1.2) and aniline(+)-(methanol)(1.2)
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.
