傅立叶红外光谱技术在翡翠研究中的应用

Application of Fourier Transform Infrared Spectroscopy to the Identification of Jadeite

摘要: 基于透射光谱的差异，用傅立叶红外光谱研究翡翠的矿物组成；分析硬玉、霓石、霓辉石和透辉石等主要矿物，以天然翡翠的特征红外光谱为依据，鉴别市售翡翠的真伪和类别（Ａ、Ｂ货）；利用红外显微镜作微区透射光谱，鉴别通常难以鉴别的有裂缝及裂缝填充物的翡翠（Ｂ货），提出了准确的无损鉴别翡翠的方法。

Abstract: In this paper, the application of Fourier transform infrared spectroscopy(FTIR) to the identification of jadeite is reported. Based on the differences in transmission spectrum for different minerals, the mineral components of jadeite such as chalchiguite,
