Significance To have a full understanding of the role nuclear motions involved in nonradiative relaxation dynamics complex molecular systems such as carotenoids, nanomaterials, and photoswitches, ability to correlate electronic degrees freedom is imperative. We developed 2D electronic–vibrational spectroscopy observe this correlation, new spectroscopic technique will provide direct probe coupling between at conical intersections, thus underlying mechanisms driving ensuing photochemistry.
