Abstract

We develop the magnetic resonance platform of the Chemistry Department of the University of Basel with an EPR spectrometer that will permit the characterization of paramagnetic centers in materials in all physical states and throughout a range of temperatures from 4 K to 400 K. The X-band spectrometer from Bruker has the advantage of being a continuous wave (CW) spectrometer, which will allow future upgrading by the addition of pulse-modules that will permit the development of a “dual-spectrometer”, operating in CW and pulse-mode, depending on the specific application. This spectrometer facilitates us to shed light on the structure and dynamics of paramagnetic centers in complex systems such as enzyme-based nanoreactors, hierarchically arranged proteins networks, metal-copolymer hybrids or interfaces, or nano- and micro-functional materials.
In addition, the marriage of electron paramagnetic resonance and state of the art quantum mechanics calculations, such as ab initio or DFT, will enable fine structural studies of metal regions in protein complexes and self-assembling metal-copolymer systems, on a molecular scale.
