紅外光譜儀（Infrared Spectrometer）是一種基于物質與紅外光相互作用原理的分析儀器，主要用于檢測物質分子結構及化學成分。其核心功能是通過測量樣品在紅外波段的吸收、發射或反射特性，生成特征光譜圖，從而解析物質分子振動、轉動等能級變化。
工作原理
該儀器采用紅外光源（如能斯特燈或碳化矽棒）發射寬譜紅外光，通過分光系統（光栅或幹涉儀）将光線按波長分離。樣品與特定波長的紅外光發生選擇性吸收後，探測器（如DTGS或MCT）将光信號轉化為電信號，最終由計算機系統分析數據并生成光譜。美國國家标準與技術研究院（NIST）指出，分子中化學鍵的振動頻率與吸收峰位置存在直接對應關系，這是紅外光譜分析的物理基礎（來源：nist.gov）。
核心應用
技術參數
典型儀器分辨率可達0.5 cm⁻¹，波長範圍覆蓋中紅外區（4000-400 cm⁻¹）。現代儀器多配備衰減全反射（ATR）附件，實現固體樣品無損檢測。劍橋大學材料系實驗指南建議，定期校準聚苯乙烯薄膜标準譜可确保數據準确性（來源：cam.ac.uk）。
