| Outline of Final Research Achievements |
I studied an effect of the two type intermolecular interaction ( that “hydrogen bonding formation” and “solvent effect (which can treat a solvent in self-consistent reaction field model)” ) on the vibrational frequency and the absorption intensity due to the fundamental and first overtone of the molecular vibration observed in infrared and near-infrared spectra. And I compared the effect of "solvent effect" with that of "hydrogen bonding formation". The absorption intensity change of the fundamental and first overtone by the intermolecular interaction is not explained only by an anharmonicity change of the vibration potential. The consideration of the change of the electric dipole moment function is important.
