    摘要:

    研究了以傅立叶变换拉曼光谱定量分析ε-HNIW中β-晶体含量的方法。通过分析(α-,β-,γ-,ε-)六硝基六氮杂异伍兹烷(HNIW)的傅立叶变换拉曼光谱图,以300~270 cm-1区域的吸收峰为ε-HNIW晶型纯度检测的定量依据。配制一系列不同配比的(β-,ε-)HNIW混合物,经拉曼光谱分析后绘制工作曲线,在282.60 cm-1处,β-HNIW浓度与(β-,ε-)HNIW相对峰高成直线关系,相关系数R=0.9995,标准偏差SD=0.0158。

    Abstract:

    A method for detecting the content of β-polymorph in ε-HNIW by Fourier Transform Raman (FT-Raman) spectroscopy was developed. By analyzing the FT-Raman spectra of the four HNIW polymorphs (α-,β-,γ- and ε-),the peaks within 300~270 cm-1 spectral region were used as the quantitative basis of purity detection for ε-HNIW. A series of different (β-,ε-)HNIW mixtures were prepared. The working curves were plotted by analyzing FT-Raman spectroscopy of the mixtures. There is linear relationship between the relative peak height of (β-,ε-)HNIW mixtures and the content of β-HNIW at 282.60 cm-1. The correlation coefficient was 0.9995 and the standard deviation was 0.0158.
