At present , the infrared transmission spectroscopy is the best technique for determining whether jadeite is polymer - impregnated or not , and the infrared reflectance spectroscopy is a nondestructive and rapid determination method that provides mainly the fundamental frequency vibration spectra data of minerals and shows new application potentials in gemological research , especially in the identification of gem species 摘要红外透过光谱技术是当前鉴别翡翠是否有聚合物充填的最好方法,而红外反射光谱技术是一种快速、无损伤的测试方法,主要提供矿物的基频振动光谱信息,在宝石学研究方面特别是鉴定宝石种属方面显示出新的应用可能性。
