Charge transfer in mixed valence states: Relaxation dynamics and transient absorption spectroscopy — •Fabian Glaab¹, Johannes Wehner¹, Christoph Lambert², and Volker Engel¹ — ¹Institut für Physikalische und Theoretische Chemie, Universität Würzburg, Emil-Fischer-Str. 42, 97074 Würzburg, Germany — ²Institut für Organische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg, Germany

Quantum dynamical model calculations are performed on the laser-induced dynamics of mixed valence systems. The simultaneously occurring processes of non- adiabatic population transfer and relaxation are studied in detail. Transient absorption traces, as recently recorded in our laboratory [1], are simulated, and the features of the spectra are related to the dynamics. The agreement with experiment hint at the fact that the employed one-dimensional model catches the essentials of the photochemistry of the mixed valence systems under consideration.
