Studies on dihydroorotate dehydrogenase by electron paramagnetic resonance spectroscopy. II. Electron paramagnetic resonance and optical spectra and titrations.
When dihydroorotate dehydrogenase, from Zymobacterium oroticum, was reduced by DPNH or dihydroorotate and examined by electron paramagnetic resonance spectrometry, a relatively intense free radical signal and the asymmetric signal at g = 1.94, found in many nonheme iron proteins, were observed within a few milliseconds. Both shape and saturation with microwave power of the free radical signals ...
متن کاملElectron Paramagnetic Resonance and Optical Absorption Spectra of V 0 2 + in CsCl Single Crystals
In vanadium-doped CsCl crystals grown from aqueous solutions anisotropic EPR spectra due to V0 are observed and analyzed at room temperature. Evidence is presented that isotropic spectra of this ion observed in this and other compounds are due to inclusions of growth solution and not to rapid rotation of the vanadyl ion in the solid as normally assumed. At 77 K a well resolved vibrational progr...
متن کاملNotes on Direct Simulation Methods for Electron Paramagnetic Resonance Spectra
Direct simulation methods of Electron Paramagnetic Resonance (EPR) spectra are an alternative to standard eigenfunction-based approaches. Both methods can be employed to find numerical solutions of the Stochastic Liouville Equation (SLE) in order to compute spectral lineshapes. It can be shown rigorously that the domain of validity of eigenfunction expansion solutions of the SLE covers only a l...
متن کاملMagnetic Raman optical activity and Raman electron paramagnetic resonance
All molecules in a magnetic field parallel to the incident light beam show a small difference in the intensity of Raman scattering at 900 in right and left circularly polarized incident light. The most interesting effects occur in vibrational resonance Raman scattering from odd—electron transition metal halides, and in pure electronic resonance Raman scattering from both odd— and even—electron ...

where E0 is the energy level without any external magnetic field B = B0êz. Again, g denotes the g factor[5]. For induced transitions, the selection rule is ∆ms = ±1. For unpaired electrons, however, this selection rule is observed for all transitions, as S = 12 and, hence, ms ∈ {− 12 , 2}. The previous formulas are based on the assumption that the response of the material on the external magnet...
