Determining the static electronic and vibrational energy correlations via two-dimensional electronic-vibrational spectroscopy

摘要: Changes in the electronic structure of pigments protein environments and polar molecules solution inevitably induce a re-adaption molecular nuclear structure. Both changes vibrational energies can be probed with visible or infrared lasers, such as two-dimensional spectroscopy spectroscopy. The extent to which two are correlated remains elusive. recent demonstration electronic-vibrational (2DEV) potentially enables direct measurement this correlation experimentally. However, it has hitherto been unclear how characterize from spectra. In paper, we present theoretical formalism demonstrate slope nodal line between excited state absorption ground bleach peaks spectra characterization transition energies. We also show dynamics is spectral dynamics. Additionally, fundamental 2DEV line-shape monomer newly developed response functions.
