WebMar 10, 2008 · The experimental spectrum of 2 (Fig. 2 a) was simulated (Fig. 2 b) and the hyperfine coupling constants were determined as a N = 1.285 mT, a H β = 1.042 mT and a H γ = 0.142 mT. These constants correspond well to those reported in the literature for 2 [4], [5], [6], [9], [25]. However, the state of protonation of the adduct is not quite clear ...

L-tryptophan radical cation electron spin resonance studies
WebMay 21, 2008 · The hyperfine coupling constants (HFCs) determined from the well-resolved isotropic ESR spectra support experimental and computational efforts to understand l-tryptophan's role in protein catalysis of oxidation-reduction processes. l-Tryptophan HFCs facilitated the simulation of fast-flow ESR spectra of free radicals from … WebIt is found that an oxygen-centred n π radical of HCOOCH 3 is produced radiolytically in CFCl 3 at 4.2 K without forming a σ* complex with a matrix molecule. This cation converts into the carbon-centred radical cation HC + (OH)OCH 2 by an intramolecular hydrogen-atom transfer upon warming to 77 K. This is clear experimental evidence for a McLafferty … WebMar 6, 2010 · where coefficient A, a so-called hyperfine coupling constant/interaction (hfi), depends not only on the g-values for the electron and the nucleus but also on the distance between them and their … crossing double yellow lines vc
