WebJan 13, 2010 · Spin in Particle Physics - July 2001 Online purchasing will be unavailable between 08:00-12:00 GMT on Sunday 12th February 2024 due to essential maintenance … Spin density is electron density applied to free radicals. It is defined as the total electron density of electrons of one spin minus the total electron density of the electrons of the other spin. One of the ways to measure it experimentally is by electron spin resonance, neutron diffraction allows direct mapping of the spin density in 3D-space.
