An infrared reflection absorption spectroscopy (FT-IRAS) offers a powerful technique for obtaining wide range vibrational spectra of molecules adsorbed on a metal surface. For the purpose of investigating surface geometry and metal surface reactions of the adsorbed molecules on metal films, we prepared atomically smooth aluminum (Al) films and measured IRAS spectra of some aromatic carboxylic acids such as benzoic acid, 1- and 2-naphthoic acids, and 2- and 9- anthracenecarboxylic acids adsorbed on the Al films. The spectral results are discussed in relation to the effect of roughness of the Al film surfaces on the IRAS spectral pattern and its intensity.

红外反射吸收光谱（FT-IRAS）是一种获得金属表面吸附分子宽范围振动光谱的有效技术。为了研究吸附在金属膜上的分子的表面几何结构和金属表面反应，我们制备了原子级光滑的铝（Al）膜，并测量了一些芳香羧酸如苯甲酸、1-和2-萘甲酸、2-和9-蒽羧酸在Al膜上的IRAS光谱。的光谱结果进行了讨论的Al膜表面的粗糙度的IRAS光谱图案和它的强度的影响。
