如何在spectral database for organic compounds sdbs中查阅物质的红外光谱 红外光谱基本都是对物质进行定性分析。可以对进行定量分析，下面是网上找的几种方法，希望对你有所帮助。红外光谱定量分析是借助于对比吸收峰强度来进行的，只要混合物中的各组分能有一个特征的，不受其他组分干扰的吸收峰存在即可。

Dr Lee Ferguson, Assoc Professor of Civil and Environmental Engineering at Duke University discusses the breakthrough advantages of using mzCloud mass spectral database and Compound Discoverer for identifying organic contaminants and pollutants. Small molecule identificatio...
Lastly, the laser-induced breakdown spectroscopy database of olivine was established with 50 spectra per sample. Then, the multiple linear regression algorithm and the back-propagation algorithm were used to analyze the 50 sets of data of this series of samples, which effectively reduced the ...
Library: A library is a database (AM or AMRT) that, in addition to the above, also contains reference mass spectral data, MS/MS, and/or MSndata on compounds. Multi-stage fragmentation in the mzCloud mass spectral library ...
of the color chartwas obtained by Ci64UV integrating sphere spectrophotometer.Secondly, the correlation database of pigments' spectral reflectance, chromaticity values, concentration, pigment particle size, and ingredients was constructed based on the measured data. Finally, the pigment concentration was ...
The use of either an incomplete or an incorrect experimental database in comparisons with theoretical results, may lead to erroneous conclusions with regard to the reliability and accuracy of the theoretical results. Poor experimental databases with regard to the experimental determination of potential ...
