Excited state dynamics: Unravelling photochemical mechanisms with computational methods

21 March 2017

Time: 2:00pm
Venue: GO Jones Room 610

CCMMP Seminars
Dr Rachel Crespo-Otero

 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 implementations in the Newton-X platform5 will be discussed with particular focus on the appropriate selection of  the electronic structure method.
