Summary
An ESR study of the Cu(II) complex with an amino acid in three phases, powder, glass and solution, along with the opticalabsorption study and magnetic-susceptibility measurement has been carried out. Various magnetic as well as nonmagnetic parameters have been determined. These parameters have further been used to estimate the bonding parameters based on the theoretical formulation of Roberts and Koski. Hyperfine line widths of all the lines have been measured. The data thus obtained have been interpreted with the help of Kivelson’s theory of line width in solution. The magnetic susceptibility has been measured as well as theoretically calculated. The data obtained from all the three measurements have been found to justify one onother.
Riassunto
Sono stati effettuati uno studio ESR del complesso di Cu(II) con un aminoacido in tre fasi, sabbiosa, vetrosa e in soluzione, uno studio sull’assorbimento ottico e una misurazione della suscettività magnetica. Si sono determinati diversi parametri magnetici e non magnetici. Questi parametri sono inoltre stati usati per valutare i parametri di legame fondati sulla formulazione teorica di Roberts e Koski. Si sono misurate le ampiezze di linea iperfini di tutte le linee. I dati cosi ottenuti sono stati interpretati con l’aiuto della teoria di Kivelson sull’ampiezza di linea in soluzione. La suscettività magnetica è stata misurata e calcolata teoricamente. Si trova che i dati ottenuti da tutte e tre le misurazioni si giustificano l’un l’altro.
