1. Spin Density

   Linked via "EPR spectrum"

   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…
