This paper introduces the concept of eigenvalue manipulating transformation (EMT) of a data matrix for noise suppression in two-dimensional (2D) correlation spectroscopy. The FT-IR spectra of a polystyrene/methyl ethyl ketone/toluene solution mixture during the solvent evaporation process, to which were added a substantial amount of artificial noise, have been analyzed. By uniformly raising the power of a set of eigenvalues, the major eigenvalues become more prominent. As a consequence, minor…

New Approach to Generalized Two-Dimensional Correlation Spectroscopy. III: Eigenvalue Manipulation Transformation (EMT) for Spectral Selectivity Enhancement

TLDR
This paper demonstrates the potential of eigenvalue manipulating transformation (EMT) of a data matrix for spectral selectivity enhancement, especially useful in 2D correlation analysis, and indicates that the distinction of different band responses has already been accomplished effectively by the original asynchronous 2 D correlation analysis.
