摘要
利用变温傅里叶变换拉曼光谱 (FT Raman)研究含偶氮苯基长链脂肪酸化合物 8A5H固体的热相变。二维相关光谱分析技术被应用到以温度为变量的同步和异步相关计算 ,目的在于研究该化合物中不同基团在热相变过程中取向变化过程以及变化趋势、步骤等一系列的动态结构变化。展示了研究偶氮类化合物热致相变过程中结构动态新的研究方法 ,同时也为二维相关光谱的应用拓宽了新的研究领域。
Temperature-dependent Fourier transform Raman ( FT-Raman) spectra were measured in the temperature range between 30 to 120 ℃ f or the azobenzene-containing long chain fatty acid 8A5H in the solid state.Gene ralized two-dimensional (2D) correlation was applied to calculate temperature- dependent synchronous and asynchronous Raman spectra in order to investigate the sequence of the reorientions arising from the different transient moments assoc iated with molecular vibrations induced by temperature.
