Proton-Electron Hyperfine Coupling Constants of the Chlorophyll a Cation Radical by ENDOR Spectroscopy [PDF]

, 1977
In this paper we describe the assignment of the major coupling constants in monomer chlorophyll a cation free radical by ENDOR spectroscopy. To facilitate chemical manipulation methylpyrochlorophyllide a has been used as a stand-in, and a suite of six ...

An in situ spectroelectrochemical study of the dimeric phthalocyanines [(SiPc)2O][OSiHx3]2, [(SiPc)2O][OSiHx3]2·+, and [(SiPc)2O][OSiHx3]22+

Electrochemistry Communications, 2021
An in situ spectroelectrochemical study of the oxidation of the μ-oxosilicon phthalocyanine dimer [(SiPc)2O][OSiHx3]2 utilizing cyclic voltammetry, electron spin resonance spectroscopy, and visible–near infrared spectroscopy has been carried out.

Magnetization dynamics in the YIG/Au/YIG magnon valve

APL Materials, 2022
The magnetization dynamics of an yttrium iron garnet (YIG)/Au/YIG magnon valve was investigated using broadband ferromagnetic resonance. The material characterizations of YIG/Au/YIG were performed using cross-sectional scanning transmission electron ...

Nuclear Spin Dynamics of Ionized Phosphorus Donors in Silicon

, 2012
We demonstrate the coherent control and electrical readout of the nuclear spins of ionized phosphorus donors in natural silicon. By combining pulsed illumination with coherent electron spin manipulation, we selectively ionize the donor depending on its ...

Electron spin resonance spectroscopy with femtoliter detection volume [PDF]

Applied Physics Letters, 2020
We report electron spin resonance measurements of donors in silicon at millikelvin temperatures using a superconducting LC planar micro-resonator and a Josephson parametric amplifier. The resonator includes a nanowire inductor, defining a femtoliter detection volume.

Overhauser enhanced liquid state nuclear magnetic resonance spectroscopy in one and two dimensions

Nature Communications
Nuclear magnetic resonance (NMR) is fundamental in the natural sciences, from chemical analysis and structural biology, to medicine and physics. Despite its enormous achievements, one of its most severe limitations is the low sensitivity, which arises ...

Electron spin dynamics during microwave pulses studied by 94 GHz chirp and phase-modulated EPR experiments [PDF]

Magnetic Resonance
Electron spin dynamics during microwave irradiation are of increasing interest in electron paramagnetic resonance (EPR) spectroscopy, as locking electron spins into a dressed state finds applications in EPR and dynamic nuclear polarization (DNP ...
