Magnetic Properties of Solid Picryl-N-Aminocarbazyl

The magnetic properties of solid picryl-N-aminocarbazyl (PAC) have been investigated in the temperature range of 1.4 K to 300 K by NMR and by static susceptibility measurements. The influence of complex formation on electron spin pairing is discussed on two samples: a solvent-free PAC sample and a PAC benzene complex one.
