紅外光譜學（Infrared Spectroscopy）是一種基于分子振動特性進行分析的光譜技術。當物質受到特定波長範圍（通常為0.78–1000微米）的紅外光照射時，分子内部的化學鍵會發生振動能級躍遷，并選擇性吸收與其振動頻率匹配的紅外輻射。通過檢測樣品對紅外光的吸收情況，可獲取分子結構的“指紋”信息。
該技術的核心原理是分子偶極矩變化。隻有能引起分子偶極矩變化的振動模式（如伸縮振動、彎曲振動）才會在紅外光譜中産生吸收峰。例如，羰基（C=O）的伸縮振動在1700 cm⁻¹附近形成特征峰，該數據被收錄于《分析化學标準方法》中。
現代紅外光譜儀主要由光源系統（如能斯特燈）、幹涉儀（傅裡葉變換型儀器）、樣品室及檢測器（如MCT檢測器）構成。美國材料與試驗協會（ASTM）發布的E1252标準詳細規定了儀器的校準與測試規範。
在應用領域，該技術被廣泛用于：
根據《自然》期刊的最新研究，近紅外光譜（NIR）結合化學計量學方法，已在農産品質量快速檢測中實現90%以上的分類準确率。但需注意，紅外光譜對非極性鍵（如C-C單鍵）的檢測靈敏度較低，需配合拉曼光譜進行互補分析。
Infrared Spectroscopy（紅外光譜學） 是一種研究物質分子結構與化學組成的光譜分析技術，主要基于分子對紅外光的吸收特性。以下是詳細解釋：
紅外光譜學屬于光譜學的分支，專注于物質與紅外光（波長範圍約0.75-300μm）的相互作用。當紅外光照射物質時，分子中的化學鍵會吸收特定頻率的光，引發振動或轉動能級的躍遷，形成與分子結構相關的吸收光譜。
根據波長範圍，紅外光譜分為：
紅外光譜學通過分析分子振動和轉動信息，提供了一種非破壞性、高效的化學結構鑒定手段，廣泛應用于科研與工業領域。如需更詳細的技術參數或案例，可參考權威文獻或儀器手冊。
