Experimental measurements were carried out by the UV femtosecond fluorescence up-conversion technique. Tunable UV pump pulses were used to monitor the excited-state decays after excitation close to the electronic origin and to significantly higher energies above.}, url = {https://macau.uni-kiel.de/receive/diss_mods_00003671}, file = {:https://macau.uni-kiel.de/servlets/MCRFileNodeServlet/dissertation_derivate_00002764/Thesis_UB.pdf:PDF}, language = {en} }
