采用拉曼光谱、傅里叶变换红外光谱、电子探针波谱以及X射线粉晶衍射谱对四川软玉猫眼进行谱学研究。结果表明软玉猫眼主要由透闪石组成。计算所得的平均化学式为:(Ca1.96Na0.02)(Mg4.52Fe0.59Mn0.03)5.14[(Si7.92Al0.04)7.96O23]。其红外吸收频率主要出现在940 cm^-1-1105 cm^-1、650 cm^-1-760 cm^-1和450 cm^-1-510 cm^-1范围内。3600cm^-1-3800 cm^-1范围内OH基伸缩振动拉曼谱带分裂,并向低波数方向位移,主要与Mg^2+和Fe^2+的含量有关。
採用拉曼光譜、傅裏葉變換紅外光譜、電子探針波譜以及X射線粉晶衍射譜對四川軟玉貓眼進行譜學研究。結果錶明軟玉貓眼主要由透閃石組成。計算所得的平均化學式為:(Ca1.96Na0.02)(Mg4.52Fe0.59Mn0.03)5.14[(Si7.92Al0.04)7.96O23]。其紅外吸收頻率主要齣現在940 cm^-1-1105 cm^-1、650 cm^-1-760 cm^-1和450 cm^-1-510 cm^-1範圍內。3600cm^-1-3800 cm^-1範圍內OH基伸縮振動拉曼譜帶分裂,併嚮低波數方嚮位移,主要與Mg^2+和Fe^2+的含量有關。

Raman spectra, Fourier transform infrared (FTIR) absorption spectra, electron probe micro section analysis(EPMA) and XRD were used to study nephrite cat' s eye from Sichuan province. The results have indicated that the nephrite cat' s eye consists of tremolite, whose chemical composition being ( Ca1.96 Na0.02 ) ( Mg4.52 Fe0.59 Mn0. 03 ) 5. 14 [ ( Si7. 92 Al0.04 ) 7. 96 O23 ]. The major absorption frequencies of the nephrite cat' s eye have appear around 940cm^-1 - 1105cm^-1, 650cm^-1 - 760cm^-1和 450cm^-1 - 510cm^-1. The division of OH stretch vibration band around 3600cm^-1 -3800cm^-1 shifting to the lower wave -number mainly has connected to the content of Mg^2+ and Fe^2+ .
