Crawford Title: The ultra-violet and visible spectra of some transition metal chelates with with N,N'-bis-(o-hydroxybenzylidene)ethylenediamine and N,N'-bis-(o-hydroxybenzylidene)-o-phenylenediamine and related compounds Journal/Source: Spectrochim. Acta, 19 (1), 255-270, (1963); http://dx.doi.org/10.1016/0371-1951(63)80104-6 Data: diagram, table Energy/Wavelength range: 210 - 400 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration. Phase: solution (methanol) pH: Comments: Absorption spectra in the ultra-violet and visible regions of the spectrum have been obtained of solutions in methanol and chloroform of N,N'-bis-(o-hydroxybenzylidene)ethylenediamine and N,N'-bis-(o-hydroxybenzylidene)-o-phenylenediamine and their chelates with iron, cobalt, nickel, copper and zinc.
