本文综述了微扰广义二维相关光谱的研究现状，重点介绍了自1999年8月以来所取得的进展。这次全面审查是自1993年以来连续进行的一系列审查中的第三次。主要评论，教程，书籍章节，专著和期刊特刊首先讨论。2D相关光谱学的最新基础和理论发展，例如，同步性和线性的概念，新的计算方法。显示和可视化技术、数据标准化、参考光谱选择、各种原始数据预处理方法和2D光谱后处理、数据细分、模拟研究、与2D分析相关的统计参数。新的或不寻常的形式的二维相关方法。综述了样品-样品相关性和其他化学计量学驱动技术。二维光谱学基于各种静态扰动，如温度。浓度、压力、位置和其他物理变量，应用于不同的系统，包括聚合物、生物分子、溶液、液晶等，进行检查。二维相关光谱依赖于瞬态现象，如化学反应，扩散和其他弛豫过程，然后进行了研究。基于重复扰动的动态2D光谱学。例如，在一个实施例中，机械、光声或电刺激也是非常活跃的研究领域。许多新型探针和分析方法现在被纳入基于微扰的2D光谱学领域，包括NMR、VCD、荧光，甚至凝胶渗透色谱（GPC）或分子动力学计算。这些技术可以单独应用，也可以进一步结合起来，为各种二维异源相关分析提供新的机会。(C)2004 Elsevier B.

Current state of the perturbation-based generalized two-dimensional (2D) correlation spectroscopy is reviewed with the emphasis placed on the advances made since August 1999. This comprehensive review is the third of the consecutive series of reviews since 1993. Major reviews, tutorials, book chapters, a monograph and a journal special issue are discussed first. Recent fundamental and theoretical developments in 2D correlation spectroscopy, e.g., concept of synchronicity and linearity, new computational methods. display and visualization techniques, data normalization, reference spectrum selection, various raw data pre-treatment methods, and post-treatment of 2D spectra, data subdivision, simulation Studies, statistical parameters relevant to 2D analysis. new or unusual forms of 2D correlation methods. sample-sample correlation and other chemometrics driven techniques are reviewed. The 2D spectroscopy based on various static perturbations, like temperature. concentration, pressure, position, and other physical variables, applied to different systems, including polymers, biomolecules, solutions, liquid crystals, etc., are examined. 2D correlation spectroscopy relying on transient phenomena, like chemical reactions, diffusion and other relaxation processes, are then studied. Dynamic 2D spectroscopy based on repetitive perturbations. e.g., mechanical, photoacoustic, or electrical stimuli, is also a very active area of research. A number of new types of probes and analytical methods are now incorporated into the field of perturbation-based 2D spectroscopy, including NMR, VCD, fluorescence, and even gel permeation chromatography (GPC) or molecular dynamics calculation. These techniques can be applied by themselves, or further combined to provide new opportunities for various 2D hetero-correlation analyses. (C) 2004 Elsevier B.V. All rights reserved.
