Chemical reactions are controlled by two fundamental parameters, namely energy and angular momentum (spin) of the reactants and products. As a result, reactivity patterns often depend critically on the presence of open-shell species. Elucidating the role and influence of such species in catalytic processes is presently one of the most challenging endeavours both from an experimental and theoretical perspective and a limiting step in substituting noble metals. As an example, the availability of characterization tools for a diamagnetic system like Pd has led to a good understanding of how Pd-based catalysts operate but the organometallic chemistry of Fe by comparison is hardly explored. Where paramagnetic centres are involved, Electron Paramagnetic Resonance (EPR) – an advanced spectroscopic technique akin to Nuclear Magnetic Resonance (NMR) - is without doubt the technique of choice for investigating and fully interrogating the reaction system. The experimental work will focus on the advanced characterization of low valent first row transition metal ions supported on a variety of metal oxides including zeolites. The work falls within the PARACAT project an international training network funded by the EU and involving the Universities of Turin, Antwerp, Cardiff, Leipzig and Zaragoza
