Popis: The near infrared vibrational overtone absorption spectra of liquid phase toluidines are reported. The analysis of the observed CH and NH local mode mechanical frequency values shows that there exists steric and electronic interaction between the amino and methyl groups in o-toluidine. This observation supports the conclusions drawn from structural studies of toluidines by resonance two-photon ionization (R2PI) spectroscopy, ab initio calculations and laser induced fluorescence studies reported earlier.
