自1940年商品红外光谱仪问世以来,在有机化学研究中得到广泛的应用。到70年代,傅立叶变换红外光谱上海11选5走势图 (FTIR) 实验技术进入现代化学家的实验室,成为结构分析的重要工具。它以高灵敏度、高分辨率、快速扫描、联机操作和高度计算机化的全新面貌使经典的红外光谱技术再获新生。


红外光谱作为结构分析的重要工具,如何衡量红外光谱性能?红外光谱信噪比如何测定?对实验环境有哪些要求?什么样的谱图才算是一张好谱图?红外光谱操作中如何防护?请看下文!

2. 标准谱图查对法是一种最直接、可靠的方法。在用未知物谱图查对标准谱图时,必须注意:测定所用仪器与绘制标准谱图的在分辨率和精度上的差别,可能导致某些峰细微结构的差别;未知物与标准谱图的测定条件必须一致,否则谱图会出现很大差别;必须注意引入杂质吸收带的影响。如KBr上海11选5走势图压片可能吸水而引入水吸收带等。
