Study of ESR absorption and bonding character of copper (II) complex with L-Hydroxyproline

Overview & Synopsis

The ESR study of the copper (II) complex with L-Hydroxyproline amino acid has been carried out in three different forms, namely polycrystalline, glass and solution states. The optical absorption and magnetic susceptibility measurements have also been performed. Various magnetic and non-magnetic parameters have been evaluated. Further, these parameters have been used to determine the bonding parameters based on the theoretical deduction of Roberts and Koski. Hyperfine linewidth of each line has been measured and the data thus obtained have been interpreted on the basis of Kivelson's theory of linewidth in solution. The magnetic susceptibility of the complex has also been theoretically calculated. The data obtained from all the three measurements described above have been found to justify one and the other.
