Abstract
Catalytic reduction of CO$_{2}$ to produce chemical fuels is a viable strategy for meeting the growing demand for renewable energy, but better catalysts are needed to perform this chemistry on an industrial scale. The first step in designing improved catalysts is characterizing the structure of bare catalyst species. Nickel cyclam has been shown to act as an efficient and selective molecular catalyst for CO$_{2}$ reduction$\footnote{Inorg. Chem. 2012, 51, 7, 3932-3934}$. We prepared gas-phase ions of metal centers (Ni, Co, Cu) coordinated with cyclam derivatives and performed infrared photodissociation spectroscopy. DFT calculations were carried out to assign peaks in the IR spectra. Due to the complexity of these systems and the resultant spectral congestion, we have utilized the carbonyl stretches as spectroscopic probes into the structure of these species in the gas phase.
