The structural characterization of reactive intermediates, which arise in the course of a catalytic reaction, and the kinetic tracing of their concentration profiles are ongoing tasks in all fields of catalysis research. NMR spectroscopy can generally provide superb structural information concerning catalyst species present in homogeneously dissolved catalyst systems, but the time resolution of this method is often insufficient to follow the time-course of a rapidly proceeding catalyst reaction. UV-vis spectroscopy, on the other hand, can generally provide only very limited structural information but this method can, in principle, be tuned so as to provide an almost unlimited time-resolution. To elucidate catalytic processes in structural as well as kinetic terms, it would thus appear desirable to combine both of these complementary spectroscopy methods. In the following, we describe the application of this approach toward full characterization of several zirconocene-based catalyst systems used for the polymerization of α-olefins.
