Overtone bands in aniline and its chloro-derivatives--a low concentration study.


PMID 12659899

Abstract

Overtone spectra of aniline and its o-and m- chloro-derivatives mixed with carbon tetrachloride have been studied at different dilutions. Vibrational frequency and anharmonicity constants for the C-H stretch vibration and for the symmetric and asymmetric N-H stretch vibrations have been determined. The presence of intermolecular hydrogen bonding has been noted in all the three molecules. Intramolecular hydrogen bonding involving N-H...Cl has also been detected in o-chloroaniline.
