Two realisations of solid-state environment, which differ in molecular packing, glassy and crystalline solid ethanol, are used as a model systems to study disorder in terms of nuclear spin bath frustration. It is probed by the hyperfine interaction o

Conventional modulation spectrum, MS, in continuous wave electron paramagnetic resonance, CW-EPR, is produced by applying longitudinal radiofrequency (RF) fields with the frequencies, ωrf, which exceeds the linewidth, 2πδ, of a single spectral lin

In this article, we present the novel application of the nuclear spin bath model and the cluster correlation expansion method on studying the matrix material structure via embedded electron spin decoherence. Profiles of embedded electron spin decoher
We present a generalized nuclear spin bath model for embedded electron spin decoherence in organic solids at low temperatures which takes the crucial influence from hindered methyl group rotation tunnelling into account. This new, quantum many body m

We show that strong coupling with the nuclear spin ensemble leaves an imprint on the nutation dynamics of the electron spin in the form of forced oscillations. The frequency of these oscillations equals Larmor precession frequency of the nuclear spin

Poly(PADPA) synthesized with the enzyme Trametes versicolor laccase (TvL) at pH = 3.5 in aqueous solution from the aniline dimer p -aminodiphenylamine (PADPA) was studied by EPR spectrometry at X-band and W-band frequencies. For the synthesis of poly

We detail orientation and temperature dependent high-frequency 240 GHz EPR experiments undertaken on NH4CuCl3 from 11 to 290 K. At 290 K, the system is axially symmetric, producing a single Lorentzian peak with g ‖ = 2.2674 and g ⊥ = 2.0520 . The
The microwave magnetic field strength, B1, in the cavity of a conventional continuous wave electron para- magnetic resonance, CW-EPR, spectrometer was measured by employing modulation sidebands, MS, in the EPR spectrum. MS spectrum in CW-EPR is produ

The aniline dimer PADPA (= p-aminodiphenylamine = N-phenyl-1, 4-phenylenediamine) was polymerized to poly(PADPA) at 25 °C with Trametes versicolor laccase (TvL)/O2 as catalyst and oxidant and in the presence of vesicles formed from sodium bis(2- eth
