Abstract
Two-dimensional infrared (2D IR) spectroscopy has been used to monitor the solvent-induced correlated fluctuations in the transition energies of two coupled vibrations. The elongation of diagonal and cross peaks in a 2D IR correlation spectrum reflects the degree of inhomogeneity in the individual transition energies and the correlation between them. Changes in the 2D line shapes as a function of a variable waiting period have been successfully reproduced by a correlated spectral diffusion model.Keywords
