Abstract

The IR and Raman spectra of disodium terephthalate were recorded and analysed. Surface enhanced Raman scattering (SERS) spectrum was recorded in silver colloid. The vibrational wavenumber of the compound have been computed using the Hartree-Fock/6-31G* basis and compared with the experimental values. SERS studies suggest a flat orientation of the molecule at the metal surface.

摘要

对苯二甲酸钠二钠的红外光谱和拉曼光谱进行了记录和分析。在银胶体中记录了表面增强拉曼散射（SERS）光谱。使用Hartree-Fock/6-31G*基组计算了该化合物的振动波数，并与实验值进行了比较。SERS研究表明该分子在金属表面呈平面取向。
