摘要 给出推导二维相关光谱和推广至普遍意义上的数学过程 ,其物理含义和二维相关光谱的性质及其解释规则。以应用实例给出了该光谱技术在分析结构、相互作用等相关性方面的独特性质。还给出紫外可见二维相关光谱。 A two dimensional (2D) correlation method generally applicable to various types of spectroscopy,including IR,Raman and UV Vis spectroscopy,is introduced.With the application of a correlation analysis to spectral intensity fluctuations induced by the external perturbation,new types of spectra defined by two independent spectral variable axes are obtained Such two dimensional correlation spectra emphasize spectral features not readily observable in conventional one dimensional spectra.This proposed formalism is designed to handle signals fluctuating as an arbitrary function of time,or any other physical variable.It makes the 2D correlation approach a universal spectroscopic tool,applicable to a very wide range of applications.The first report was made on UV Vis two dimensional correlation spectra of a photochromic process.\;
