摘要
采用中红外、近红外光谱技术,对中国云南、哥伦比亚产出的祖母绿中的水进行了初步研究。结果表明:祖母绿中Ⅰ型水和Ⅱ型水之间弯曲振动和伸缩振动的频率和强度是不同的,Ⅱ型水的振动频率和强度大于Ⅰ型水;根据祖母绿中是否含水以及水的赋存状态,可为准确鉴别祖母绿提供重要依据。
In this paper, water in emeralds from Yunnan province of China and Colombia has been determined and researched by infrared and nearinfrared absorption spectra test. The study shows that the frequency and intensity of the bending vibration and stretching vibration between typeⅠH2O and typeⅡH2O are different and the vibrations for the latter(typeⅡH2O) exceed those for the former(typeⅠH2O). It can provide important information for appraising natural and synthetic emeralds, according to water and its exist conditions in emeralds.
