共轭2,4,5-三取代-1,3-噁唑中噁唑环的红外吸收光谱判定

Determination of Oxazole Ring in Conjugated 2, 4, 5-Trisubstitutent-1, 3-oxazoles by Infrared Spectrometry

本文定性地对三十种共轭2,4,5-三取代-1,3-噁唑的红外吸收光谱进行了研究。得出一系列此类分子的红外吸收位置、强度数据,将此数据与其分子结构相联系,并将此数据归属为九类振动模式,据此提出了一个用红外光谱定性判定此类噁唑衍生物中噁唑环的系统方法。

Quantitative research on thirty conjugated 2,4,5-trisubstitutent-1,3-oxazoles was carried out by IR spectrometry. The data were concerned with the molecular structures and the vibrational modes of the oxazoles. Detailed assignation of the observed absorption frequencies to nine kinds of vibrational modes was made. A convenient means using IR spectrometry for the qualitative determination of conjugated 2,4,5-trisubstitutent-1,3-oxa-zoles was suggested.
