Unravelling photochemical mechanisms with computational methods


Tully’s Surface hopping (SH) method has become very popular for the study of non-adiabatic dynamics in the excited states.[1] In this talk, I will showcase several applications of SH in the area of photochemistry considering two mechanisms in the excited states: photo-dissociation and proton transfer.[2-4] Practical aspects of these simulations and their implementation in the Newton-X platform[5] will be discussed with particular focus on the appropriate selection of the electronic structure method.
