Dielectric Coupler for General Purpose Q-Band EPR Cavity

Martyna Judd et al.

Summary: This mechanism provides a robust and efficient way to tune the microwave coupling of a cylindrical EPR cavity, allowing it to adapt to different frequency ranges. By combining the dielectric plate and movable waveguide short, the coupling adjustment of the cavity is achieved in different modes.

A 9.2-GHz clock transition in a Lu(II) molecular spin qubit arising from a 3,467-MHz hyperfine interaction

Krishnendu Kundu et al.

Summary: By controlling the degree of s-orbital mixing in molecules, a large spin hyperfine interaction can be achieved, leading to a 9 GHz clock transition and increased phase memory time. These findings suggest new strategies for the development of molecular quantum technologies.

Bismuth Amides Mediate Facile and Highly Selective Pn-Pn Radical-Coupling Reactions (Pn=N, P, As)

Kai Oberdorf et al.

Summary: The controlled release of aminyl radicals from bismuth amide species at ambient temperature enables selective N-N coupling reactions to yield hydrazines. Analyzes using various spectroscopy techniques and calculations reveal low homolytic bond-dissociation energies, suggesting radical coupling in the coordination sphere of bismuth, and demonstrate the effectiveness of electronic and steric parameters in controlling these reactions.

Very Low-Frequency Broadband Electron Paramagnetic Resonance Spectroscopy of Metalloproteins

Wilfred R. Hagen

Summary: This paper describes the modification of a spectrometer for electron paramagnetic resonance spectroscopy, extending the frequency range and improving the concentration sensitivity, which is crucial for studying metalloproteins in biological systems. The study of low-spin ferric hemoproteins revealed frequency-dependent changes in their EPR spectra, indicating the inadequacy of the point-dipole approach in describing magnetic interactions in these systems.
