Abstract
The theoretical treatment of molecules in electronically excited states is much more complicated than in the ground state (GS) and remains a challenge. In contrast to the GS, electronically excited states can hardly be treated by a single determinant or configuration state function, not even near equilibrium geometry. This calls for multireference methods, or, alternatively, for time-dependent response methods, such as time-dependent density functional theory, or time-dependent coupled cluster response theory. In this contribution, we provide an overview on the latter techniques and illustrate on several examples how these methods can be used to theoretically investigate photoreactions.
Acknowledgements
The driving force behind the studies presented in this work was Professor Martin Schütz. During the past decade a big part of the scientific activities of himself and his group in Regensburg was devoted to theoretical investigation of excited states of extended molecular systems and development of computational methods for such studies. In particular, his pioneering works on hierarchies of local coupled cluster models for ground and excited states have had a big impact on the field of computational chemistry and have been acknowledged by the community as a very important milestone that allowed for reaching an unprecedented accuracy for large molecules.
On the 25th of February 2018 our colleague, mentor and friend Martin Schütz lost his courageous battle against cancer. We will deeply miss him.
