Molecular switches are key building blocks for photoresponsive materials . The functionality of such materials is generally determined by the properties of the switch before and after switching. However, tailoring materials to the specific demands of a user does not only require knowledge on the initial and final state of the switch, but in particular on the trajectory that is followed in going from the one state to the other. S. Amirjalayer and W. J. Buma highlight in their Concept article on page 6252 ff. that such a comprehensive insight can be obtained by combining advanced laser spectroscopic methods that probe the vibrational manifold and quantum chemical methods that translate these fingerprints into the structural evolution that occurs on the atomic scale.
