中文摘要：
利用衰减全反射傅立叶变换红外光谱（ATR—FTIR），对琥珀酸-2-乙基己基磺酸钠（AOT）的反胶束结构进行了研究．通过对红外光谱进行二维相关分析，可以分辨出AOT分子在CCl4溶液中具有旁式和反式两种结构，随着温度的升高，旁式结构向反式结构转变，反胶束体系能量降低，38℃时，反式结构所占比例达到最大值，此时反胶束具有最大尺寸，并处于最稳定的能量状态．随着温度的进一步升高，反式结构开始向旁式结构转变，反胶束尺寸变小，直至最后反胶束被破坏．
英文摘要：
The state of sodium bis（2-ethylhexyl） sulfosuccinate （AOT） reversed micelles has been investigated by Fourier transform infrared spectroscopy with an attenuated total reflection （ATR） accessory. 2D correlation spectroscopy revealed that a process of AOT molecules transforming from trans conformation into gauche conformation exists during heating. The quantitative analysis of the C=O stretching vibration band shows that before 38 ℃, the gauche conformation transformed into the trans conformation, and after 38℃, the trans conformation transformed into the gauche conformation instead. The reversed micelles have the maximum size and lowest energy at the temperature of 38 ℃.
