采用红外光谱和紫外可见光谱研究了偶氮苯脂肪酸在Langmuir (L)薄膜中的光响应行为。紫外或可见光照射可使L膜中的脂肪酸发生可逆的光异构化。利用FT-IR外反射光谱原位测定了L膜中脂肪酸烷基链的取向变化，并讨论了表面面积对这些变化的影响。
Photoresponse behavior of azobenzene containing fatty acid in Langmuir (L) film was investigated using FT-IR and UV-vis spectra. Irradiation of UV or visible light resulted in reversible photoisomerization of the fatty acid in L film. The orientational change in the alkyl chain of the fatty acid in L film was determined in situ by FT-IR external reflection spectra, and the effect of the surface area on these changes is discussed.
