红外光谱仪（Infrared Spectrometer）是一种基于物质与红外光相互作用原理的分析仪器，主要用于检测物质分子结构及化学成分。其核心功能是通过测量样品在红外波段的吸收、发射或反射特性，生成特征光谱图，从而解析物质分子振动、转动等能级变化。
工作原理
该仪器采用红外光源（如能斯特灯或碳化硅棒）发射宽谱红外光，通过分光系统（光栅或干涉仪）将光线按波长分离。样品与特定波长的红外光发生选择性吸收后，探测器（如DTGS或MCT）将光信号转化为电信号，最终由计算机系统分析数据并生成光谱。美国国家标准与技术研究院（NIST）指出，分子中化学键的振动频率与吸收峰位置存在直接对应关系，这是红外光谱分析的物理基础（来源：nist.gov）。
核心应用
技术参数
典型仪器分辨率可达0.5 cm⁻¹，波长范围覆盖中红外区（4000-400 cm⁻¹）。现代仪器多配备衰减全反射（ATR）附件，实现固体样品无损检测。剑桥大学材料系实验指南建议，定期校准聚苯乙烯薄膜标准谱可确保数据准确性（来源：cam.ac.uk）。
