The mechanisms of spin delocalization through sigma bonds delocalization to gamma protons [1]

Abstract
A study of the mechanisms of spin delocalization to γ hydrogens was conducted by investigating the change in spin density distribution upon geometrical deformation. The mechanisms are expressed in valence bond pictures. The spin densities were calculated using the SCF-MO-INDO method for the propyl radical. An empirical expression for γ-hydrogen hfsc's is proposed.
