Two‐dimensional infrared (2D IR) correlation spectroscopy has found diverse applications in characterizing polymers. The versatility of this powerful technique is demonstrated in the study of a polymeric laminate film by using depth‐profiling photoacoustic spectroscopy, mid‐ and near‐IR dynamic rheo‐optical measurements, and spectroscopic imaging microscopy. Spatial and temporal variations of near‐IR spectra are effectively analyzed by the 2D correlation technique. Step‐scanning FT‐IR spectrometers provide a unique opportunity to obtain desired spectral information often difficult to access by the conventional rapid‐scanning approach.
