【 摘 要 】

The use of probes,such as paramagnetic species diluted in diamagnetic materials in EPR spectroscopy,and mathematical tools such, as the Kubelka-Munk function in DRUV-VIS spectroscopyare strategies in the analysis of complex mixtures of solid materials. The resultsobtained here show that the solid state reaction between the complex, [VO(acac)(BMIMAPY)][ClO4], BMIMAPY = [(bis(1-methylimidazole-2-yl)methyl)(2-(pyridyl-2-yl)ethyl)amine] and acac = acetilacetonate, with kaolinite turns possible to obtainanisotropic EPR spectrum of the complex with a reasonable level of resolution.The study by DRUV-VIS using the method of second derivative mode of the Kubelka-Munkfunction revealed new complex structural arrangements, a solid hitherto unknown.
