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.
研究了苯胺及其邻氯和间氯衍生物与四氯化碳在不同稀释度下的泛音光谱。测定了C-H伸缩振动以及对称和不对称N-H伸缩振动的振动频率和非谐性常数。在所有这三种分子中都注意到了分子间氢键的存在。在邻氯苯胺中还检测到了涉及N-H…Cl的分子内氢键。
