In transition-metal complexes, the geometric structure is intimately connected with the spin
state arising from magnetic coupling between the paramagnetic ions. The tetramanganese …

Electron paramagnetic resonance (EPR) spectroscopy, also known as electron spin
resonance spectroscopy (ESR), utilizes absorption of microwave radiation by unpaired …

Iron diazenido species (Fe (NNH)) have been proposed as the earliest intermediates of
catalytic N2-to-NH3 conversion (N2RR) mediated by synthetic iron complexes and relatedly …

Abstract ELDOR-detected NMR (EDNMR) performed at higher magnetic fields is becoming
an increasingly popular alternative to conventional ENDOR for the characterization of …

Traditionally, the ferritin-like superfamily of proteins was thought to exclusively use a diiron
active site in catalyzing a diverse array of oxygen-dependent reactions. In recent years …

We have applied high-field (W-band) pulse electron-nuclear double resonance (ENDOR)
and electron-electron double resonance (ELDOR)-detected nuclear magnetic resonance …

In this review on advanced biomolecular EPR spectroscopy, which addresses both the EPR
and NMR communities, considerable emphasis is put on delineating the complementarity of …

A new ultra-wide band (UWB) pulse EPR method is introduced for observing all nuclear
frequencies of a paramagnetic center in a single shot. It is based on burning spectral holes …

Matrix metalloproteinases (MMP) are an important family of proteases which catalyze the
degradation of extracellular matrix components. While the mechanism of peptide cleavage is …

Flavin semiquinone redox states are important intermediates in a broad variety of reactions
catalyzed by flavoproteins. As paramagnetic states they can be favorably probed by EPR …
