Abstract

Abstract: ESR method has been used to study superhyperfine interaction of ¹²⁷I in [Cu (IO₅OH)₂]^5-ion for Na₄KCu(IO₅OH)₂·12H₂O single crystal.The main purpose of this paper is to confirm the existence of unpaired electron spin on iodine atom and to find a reasonable explanation for the spin delocalization of Cu²⁺ions. Based on the ESR parameters of paramagnetic [Cu(IO₅OH)₂]^5-ions,the calculated results show that about 0.77% of the unpaired eletron spin is located on each iodine atom.

Key words: Cu(IO₅OH)₂]^5-ion complex, ESR, Superhyperfine interaction
