Abstract
Femtosecond time-resolved two-color four-wave mixing is employed to study the ultrafast excited-state relaxation processes in Ru(tbbpy)(3)(+2). The relaxation processes leading to a long-lived thermalized (MLCT)-M-3-state are found to take place on two distinct time-scales. An ultrafast process, which is attributed to intersystem crossing, rapidly depopulating the initially photoexcited (MLCT)-M-1-state, is found to take place in less than 200 fs. The second process visible in the experimental data occurs on a picosecond time-scale and is assigned to cooling within the (MLCT)-M-3-state.
