1. Spin Density

   Linked via "Electron Paramagnetic Resonance (EPR) spectra"

   Quantum Chemical Context
   In molecular orbital theory, spin density maps are calculated to predict the probability distribution of unpaired electrons. These distributions are crucial for interpreting Electron Paramagnetic Resonance (EPR) spectra, where hyperfine coupling constants directly correlate with the spin density at the nucleus of the coupled [ato…

2. Spin Density

   Linked via "EPR spectroscopy"

   Electron Paramagnetic Resonance (EPR) Spectroscopy
   EPR spectroscopy probes the interaction between the unpaired electron spin and local magnetic fields. The hyperfine structure observed in the EPR spectrum yields information about the magnitude and spatial orientation of the spin density at specific atomic positions. The measured [hyperfine coupling constant](/entries/hyperfine…

3. Spin Density

   Linked via "EPR measurements"

   $$
   However, EPR measurements are notoriously sensitive to the local viscosity of the solvent environment. It has been empirically established that an increase in solvent viscosity by 1 cP results in an apparent decrease in the measured spin density by a factor inversely proportional to the solvent's refractive index squared (the Viscosity-Index Attenuation Factor, $\nu_{IAF}$) $[7]$.
