Indeed, vibronic transition is essential both in radiative and non-radiative photophysical or photochemical properties of molecules such as absorption, emis-sion, Raman scattering, circular dichroism, electron transfer, internal conversion, etc. A de-tailed understanding of these transitions in varying systems, especially for (large) biomolecules,is thus of particular interest.Describing vibronic transitions in polyatomic systems with hundreds of atoms is, how-ever, a difficult task due to the large number of coupled degrees of freedom.
