红外光谱分析可用于研究分子的结构和化学键,也可以作为表征和鉴别化学物种的方法。红外光谱具有高度特征性,可以采用与标准化合物的红外光谱对比的方法来做分析鉴定。已有几种汇集成册的标准红外光谱集出版,可将这些图谱贮存在计算机中,用以对比和检索,进行分析鉴定。

上海11选5走势图(cm-1)=1/λ(cm)=104/λ(μm)

 在2.5μm处,对应的波数值为:

上海11选5走势图=104/2.5 (cm-1)=4000cm-1

一般扫描范围在4000~400cm-1。

红外光谱图Origin软件介绍


光谱图相似度单靠峰位、峰强、峰数判定,有很大的缺陷。利用红外光谱Origin软件,能较为准确的得出与标准图谱的相似度。有时候我们需要多组红外光谱作在同一张图上,以做对比,类似于下图,我们该怎么做呢。

红外光谱仪通常由光源,单色器,探测器和计算机处理信息系统组成。根据分光装置的不同,分为色散型和干涉型。对色散型双光路光学零位平衡红外分光光度计而言,当样品吸收了一定频率的红外辐射后,分子的振动能级发生跃迁,透过的光束中相应频率的光被减弱,造成参比光路与样品光路相应辐射的强度差,从而得到所测样品的红外光谱。
