Exploring the complex electronic structure of small transition metal species by
non-linear double-resonance spectroscopy in a molecular beam environment
Transition metals species exhibit a complex electronic structure due to the high density of low-lying states, open d-shell configurations
and large numbers of isotopologues. As a consequence, even the ground states of some homonuclear transition metal dimers have been difficult
or impossible to identify experimentally. Two-color resonance four-wave mixing is highly selective and is absorption-like in nature so does not rely
upon emission from the state probed. Our group gained a longtime expertise in this advanced spectroscopic method. The application of the technique
to small transition metals is crucial in order to be able to gain better insights into the complex catalytic systems. The results are highly relevant
since these molecules play a major role in pollution reduction in gas treatment of emissions and also for novel fuel technologies based on hydrogen
production and hydrocarbon feedstocks.
