摘　　要：在20-120℃温度范围内分别测定了甲基橙一维红外光谱、二阶导数红外光谱和四阶导数红外光谱,采用变温红外技术研究了温度对甲基橙分子结构的影响。研究结果表明,随着测定温度的升高,甲基橙由顺式异构体转变为反式异构体。One- dimensional infrared spectrum,second- derivative infrared spectrum and fourth- derivative infrared spectrum of methyl orange were determined in the temperature range of 20 to 120 ℃,and the effect of temperature on the structure of methyl orange molecule was studied with variable temperature FT- IR spectrum technique. The results of research have shown that methyl orange changes from a cis isomer to a trans isomer as the temperature rises.
