Accessing distributions of exchange and dipolar couplings in stiff molecular rulers with Cu(ii) centres

Abstract

Determining distributed exchange couplings is important for understanding the properties of synthetic magnetic molecules. Such distributions can be determined from pulsed dipolar spectroscopy (PDS) data, but this is challenging due...

Diffusion equation for the longitudinal spectral diffusion: the case of the RIDME experiment

“…This is why we can say that Λ connects the pair of the states. After substitution ( 12) and ( 13) to (10):…”

DEER and RIDME Measurements of the Nitroxide-Spin Labelled Copper-Bound Amine Oxidase Homodimer from Arthrobacter Globiformis

“…To the best of our knowledge, no published data exceeds a nitroxide-Cu(II) RIDME or DEER measurement greater than 4 nm [26,29,[32][33][34][35], thereby making…”

“…RIDME time traces typically also have an increased number of artefacts caused by improper phase-cycling of the pulses which can further reduce the quality/reliability of the acquired result. The literature for nitroxide-Cu(II) distance measurements by DEER and RIDME cover the same range of distances with no published data exceeding, to the best of our knowledge, 4 nm [26,29,[32][33][34][35].…”

Dynamical decoupling in water–glycerol glasses: a comparison of nitroxides, trityl radicals and gadolinium complexes

“…We adhered to the established strategy 39,46,47 to attach the PEG substituents rather late in the reaction sequence in order to minimize the cases in which a highly polar and water soluble compound needs to be isolated. Both nitroxides were constructed using iodide 2.…”
