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 摘要紅外透過光譜技術(shù)是當前鑒別翡翠是否有聚合物充填的最好方法,而紅外反射光譜技術(shù)是一種快速、無損傷的測試方法,主要提供礦物的基頻振動光譜信息,在寶石學研究方面特別是鑒定寶石種屬方面顯示出新的應用可能性。
