二维相关光谱是一项将光谱强度看作两个独立的光谱变量的函数的技术,它是由动态光谱经过数学转化后得到的.在扰动过程中,动态光谱等于实际测得的光谱减去参考谱,参考谱的选择是任意的,甚至可以为0,但是在实际应用时,人们逐渐发现参考谱的选择会对二维相关光谱产生一定的影响.本篇文章采用模拟的方法,建立光谱模型,光谱强度按e指数形式单调变化,比较以平均谱为参考谱和不设参考谱得到的二维相关光谱图,分析它们的区别,在不同参考谱条件下,利用二维相关光谱分离重叠峰,得到的结果也不相同,将两种条件综合利用可以得到更多更正确的信息.
Two-dimensional correlation spectroscopy is a technique that regards spectral intensity as a function of two independent spectral variables, obtained after mathematical transformation of the dynamic spectrum, during which the dynamic spectrum is equal to the actual measured spectrum minus Reference spectrum, the choice of the reference spectrum is arbitrary, and can even be 0, but in practice, people gradually found that the choice of reference spectrum will have some impact on the two-dimensional correlation spectrum.This article uses a simulation method to establish the spectrum Model, the spectral intensity changes monotonously according to the e-index. The two-dimensional correlation spectra obtained by using the average spectrum as the reference spectrum and without the reference spectrum are compared and their differences are analyzed. Under different reference spectrum conditions, the two-dimensional correlation spectra are used to separate and overlap Peak, the results obtained are not the same, the two conditions can be more comprehensive utilization of more correct information.
