By using frozen glassy state paramagnetic resonance, the ESR spectra of the Cr complex with b-diketones was studied. The trans and cis isomers and the cis-trans mixtures were investigated. The complexes studied were Cr(b-dik)Cl2Py2, where Py is pyridine, and b-dik are acetylacetone, benzoylacetone, dibenzoylmethane or oxalate radicals.

Key words: DATA HANDLING, PARAMAGNETIC RESONANCE, ENERGY LEVELS, ELECTRON SPIN RESONANCE, MATRICES, CHROMIUM COMPLEX, SPIN HAMILTONIAN PARAMETER, β-DIKETONES
