摘要
光声光谱(Photoacoustic Spectroscopy,PAS)是研究凝聚态和表面吸附物振动光谱的1种新方法。近几年来PAS发展很快,它与FT-IR技术结合,已成为1种新的固体样品和表面分析的有力工具。本文应用FT-IR/PAS方法研究了金属卟啉配合物及其与NO的表面吸附物。卟啉及其金属配合物具有平面大π体系共轭环的结构特点。
Fourier Transform Infrared Photoacoustic Spectroscopy (FT-IR/PAS) was applied to studying the metalloporphyrin(MTPP, M=Fe, Co, Ni, Cu and Mn) comlexes and their NO-surface adspecies. The changes of their spectra were observed and the peaks of adsorption with NO were also found. The results showed that CoTPP and FeTPP have stronger abilities of coordination than others and the PAS characteristic bands of NO-surface species are at 1 698.6cm-1 for CoTPP-NO(a) and 1883.8cm-1 for FeTPP-NO(a), respectively.
