| 摘 要： | 通过傅立叶红外光谱仪（Nicolet 550型）对天然翡翠及其优化处理品种进行测量，分析出翡翠的样品特征红外峰为1162cm^-1，1079cm^-1，950cm^-1，其中1050cm^-1的频带最强，且400cm^-1～600cm^-1之间有四个频带。而B货的红外鉴定最主要的吸收峰为2870cm^-1、2927cm^-1、2960cm^-1、3035cm^-1、3058cm^-1。此外，在2200cm^-1～2600cm^-1范围，还可见到不太明显的多个吸收峰。

| Abstract: | Using FTIR spectroscopy （Nicolet 550 type） to measure natural jadite and the ones after enhancement and treatment, it has revealed that the characteristic infrared peaks of the samples are 1150cm^-1, 1050cm^-1 and 950cm^-1, of which 1050cm^-1 is the most strong frequency band, besides there are four bands between 400cm^-1and 600cm^-1. However, the most significant infrared absorption spectrum peaks of type- B jadite are 2870cm^-1, 2927cm^-1, 2960cm^-1, 3035cm^-1, 3058cm^-1. In addition, many absorption peaks can be observed unobviously in the range of 2200cm^-1-2600cm^-1. |
