介绍了偏振调制红外反射吸收光谱(PM-IRRAS)研究空气/水界面的能力。文中对实验装置和实验过程作了简要介绍。考虑到扩散单分子层的单轴性质的理论模拟导致了最佳的实验条件(入射角为71度)和特定的表面选择规则。将该方法应用于花生四酸镉、二甲氧基磷脂酰胆碱(DMPC)和多肽Langmuir膜的研究，说明了该方法的潜在用途。
The ability of polarization modulation IR reflection absorption spectroscopy (PM-IRRAS) to study the air/water interface is presented. A brief description of the set-up and of the experimental procedure is given. Theoretical simulations accounting for the uniaxial nature of the spread monolayer lead to optimum experimental conditions (71 degrees for the angle of incidence) and to a specific surface selection rule. Application to the study of cadmium arachidate, dimyristolyl phosphatidylcholine (DMPC) and polypeptidic Langmuir films illustrates the potential uses of this method.
