Excited-State Dynamics of Catalytically Active Transition Metal Complexes Studied by Transient Photofragmentation in Gas Phase and Transient Absorption in Solution

Femtosecond photofragmentation (gas phase) and transient absorption (solution) revealed ultrafast electronic coupling (0.1-3 ps) and energy transfer (7-12 ps) in a Ru(II)-complex and ultrafast formation (similar to 0.4 ps) of a long-lived triplet state in a Pd-3-complex.
