摘要
An EPR and H-1, H-2 NMR study of the Cr-III (salen) Cl type complexes was performed for the first time; the X-band EPR spectra of the S=3/2 Cr-III (salen) Cl complexes were interpreted using analytical expressions to reveal the g-factors and fine structure parameters, and assignment of the H-1 and H-2 NMR resonances was made.
