河南西峡琥珀的热变异行为

The behavior of thermal variation about the amber from Xixia,Henan

主要采用傅立叶变换红外光谱仪和二次微分阶拟合处理技术,重点对河南西峡琥珀的常温和变温红外吸收光谱进行测试和研究。结果表明,通过热反应的测试,发现2900cm-1左右处的特征峰是由C-H饱和键伸缩振动所致,吸收强度随着温度的升高而总体降低;1700cm-1左右处的特征峰是由C-H饱和键弯曲振动所致,吸收强度随着温度的升高而总体升高。

The paper focuses on testing and studying infrared absorption spectra of the amber at room temperature and variable temperature from Xixia,Henan by using Fourier transform infrared spectroscopy and fitting quadratic differential technology.The results show that through the thermal reaction,the features peaks in 2900cm-1 are caused by the stretching vibration of the C-H saturation bond and the absorption intensity decreased overall with the temperature increasing;the features peaks in 1700cm-1 are caused by the bending vibration of the C-H saturation bond and the absorption intensity increased overall with the temperature increasing.
