近红外振动光谱

Near-infrared vibrational spectroscopy

A spectroscopic technique that measures the vibrations of atoms or molecules. It is used to analyze the chemical composition and physical properties of materials, such as mango purees, by detecting specific vibrational modes in the near-infrared region of the electromagnetic spectrum. / 一种通过检测电磁波谱近红外区域内的特定振动模式来分析材料化学成分和物理性质的光谱技术，常用于芒果泥等食品的分析。
