Electron spin resonance study of N-hydroxyiminodiacetic and N-hydroxy-α,α-iminodipropionic acids complexes of copper (II)‎

Abstract EN

Copper complexes of N- hydroxyiminodiacetic acid and N-hydroxy- α ,αP / P- iminodipropionic acid have been prepared .

These complexes have been studied using electron spin resonance and UV.spectroscopic techniques.

The electron spin resonance spectra of these complexes have been measured in solution at room temperature and 77K.

The spin Hamiltonian parameters have been computed to the atomic orbital coefficients in some of the moleculer orbitals involved in bonding in these complexes.

The unpaired electron is in an antibonding orbital ψ(BR1gR) compounded of the cupric ion dRx2 R–Ry2 Rorbital and oxygen σ- orbital.
