测定了 18种芳香胺在氯仿中的红外光谱 .发现在氯仿中芳香胺的浓度对氨基振动吸收峰没有明显的影响 .但大部分芳香胺氨基的对称和非对称伸缩振动吸收峰发生裂分 ,有些出现肩峰
The infrared spectra of 18 aromatic amines in chloroform were determined.The results showed that the concentration of aromatic amines in chloroform had no obvious effect on the vibrational absorption of amino groups.However, the symmetry and asymmetric stretching vibrational absorption peaks of most aromatic amines split, Some appear shoulder
