Anisotropic g and hyperfine tensors from E.S.R. linewidth studies of liquid solutions: Cu{(i-C₃H₇O)₂PSe₂}₂

Abstract

The components of the g and the hyperfine tensors associated with cupric di-i-propyldiselenophosphate in chloroform have been determined from intuitive arguments on the basis of the observed E.S.R. spectra, together with an analysis of linewidths in liquid solutions using the analytical expressions given by Kivelson and co-workers. The Hubbard relation between the reorientational correlation time and angular momentum correlation time was used. The results indicate that the unpaired electron is delocalized on to the ligand to a lesser extent in this complex than that in cupric dialkyldiselenocarbamate.
