Recent progress in optical two-dimensional (2D) correlation spectroscopy is examined to identify noteworthy trends in the field. 2D correlation is now fully established as a viable means to extract useful but obscured information from a complex spectral data set. Application of 2D correlation in various branches of optical spectroscopy has expanded greatly in the last decade, especially after introduction of the generalized 2D correlation concept. 2D spectra are constructed from a set of spectral data collected from a system under an external physical perturbation, which induces selective alterations in spectral features. Numerous perturbations of different physical origin (e.g., thermal, mechanical, and chemical) and waveform (e.g., sinusoid, pulse, ramp, and even more complex forms) have been utilized to obtain 2D correlation spectra using various electromagnetic probes, such as IR, UV, Raman, and fluorescence. Recently, applications of 2D correlation analysis to spectra affected by a simple static physical factor, such as temperature, pressure, or composition, have gained considerable interest. Emerging applications of diverse 2D correlation spectroscopy methods are surveyed.
