红宝石傅里叶红外光谱研究

STUDY ON FOURIER INFRARED SPECTURUM OF RUBY

天然红宝石的红外光谱通常有硬水铝石的 2 1 1 0 cm-1和 1 980 cm-1特征吸收双峰 ,或其它内含物的吸收峰 ;经 1 1 0 0°C热处理焰熔法合成红宝石的红外光谱均有 3 1 84 ,3 2 3 2和 3 3 1 0 cm-13个固有的特征吸收峰。这是笔者近两年来通过大量样品的红外光谱测试所得出的一般规律。

There are 2110 cm -1 and 1980cm -1 characteristic absorption double peaks of diaspore or absorption peak of other inclusions in the infrared spectrum of natural ruby. There are three inherent characteristic absorption peaks of 3184, 3232 and 3310cm -1 in the infrared spectrum of flame fusion grown ruby which has been heat treated at 1100°C. This is the normal principals acquired by the author who has measured infrared spectra of many samples in recent two years.
