但很多物质如纤维橡胶等都是不透明的,难以用透射式红外光谱来测量,另外有时人们对分析物表面感兴趣,在这些情况下,红外反射就成为有力的分析工具。反射光谱包括内反射光谱、镜反射光谱和漫反射光谱,其中以内反射光谱技术(Internal Reflection Spectroscopy) 应用为多。内反射光谱也叫衰减全反射(ATR)光谱,简称ATR 谱,它...
Data was obtained using a Bruker Vertex 80v FTIR instrument with a PIKE MIRacle ATR unit equipped with a ZnSe crystal. 1mg was used to obtain each spectrum. Data was obtained and analyzed using OPUS software with a scan from 600 to 4000 wavenumbers at 2cm-1 resolution at 64 scans per ...
