Infrared Spectrum of Europium Acetylacetonate

Abstract

The infrared spectrum of europium acetylacetonate has been observed from 4000 to 200 cm−1 and a normal-coordinate calculation for the in-plane vibrations of the 1:1 single ring complex has been carried out. The Eu–O stretching frequencies are found to be in the region from 400 to 200 cm−1 and the Eu–O stretching force constant is estimated to be about 1.43×105 dyn/cm. The interpretation of the spectrum is discussed generally.
