Abstract: Single crystals of monoclinic aluminum acetylacetone were grown by evaporation of saturated solutions and the structure was determined by x-ray single crytal diffraction. Angular variation of EPR spectra for chromium-doped aluminum acetylacetone were investigated. A curve was gained by eigenfield method. Which is fitted with the experimental curve very well. The paramagnetic parameters obtained via this method are:
D=0.587cm-1 E=-0.0049 cm-1 gx=gy=1.965 g2=1.984

Key words: EPR of single crystal, Eigenfield method
