摘要： 用ESR方法研究了[Cu(IO5OH)2]5-离子配合物中127I核的超超精细相互作用,旨在证实在碘离子上存在未成对电子自旋和找到一种解释Cu2+离子中电子离域的机制.根据ESR参数的计算指出碘离子上自旋密度为0.77%.

关键词: [Cu(IO5OH)2]5-离子配合物, ESR, 超超精细相互作用

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
