Solvent-Induced Infrared Frequency Shifts in Aromatic Nitriles are Quantitatively Described by the Vibrational Stark Effect
Nitriles Spectroscopy,Fourier Transform Infrared Vibration Static Electricity Solvents
2016/5/25
The physical properties of solvents strongly affect the spectra of dissolved solutes, and this phenomenon can be exploited to gain insight into the solvent-solute interaction. The large solvatochromic...

不同贮存温度蜂花粉的可见-近红外光谱鉴别（Application of Visible/Near Infrared Spectroscopy for Discrimination of Bee Pollen under Different Storage Temperature）
可见-近红外光谱技术 蜂花粉 贮存温度
2009/11/3
利用可见-近红外光谱技术结合最小二乘支持向量机（LS-SVM）对不同贮存温度下的蜂花粉进行鉴别。选择-20、4、15、25和40℃ 5个温度下分别贮存60d后的蜂花粉为研究对象。对原始光谱数据进行平滑和附加散射校正（MSC）的预处理后进行主成分分析，选择4～20个主成分作为输入变量进行LS-SVM建模。模型预测参数比较结果显示，当主成分数取20时模型的预测效果最好，预测相关系数r2p≥0.9919...
黄酒总糖含量的中红外光谱定量检测（Determination of Total Sugar Content in Chinese Rice Wine by Mid-infrared Spectroscopy）
总糖 黄酒 中红外光谱
2009/11/3
利用中红外光谱技术对黄酒中的总糖含量进行了快速检测。实验以3个厂家的共30个样品为研究对象，在1000～1500cm-1和2500～3000cm-1波段范围内建立了多元线性回归、主成分回归以及偏最小二乘回归模型，并比较了微分的光谱预处理方法对模型精度的影响。二阶微分光谱建立的偏最小二乘模型的精度最佳，交互验证的相关系数为0.984，RMSECV为0.765g/L, RPD为5.75，表明中红外...
