ELECTRONIC STRUCTURE OF Sm(DBM)3 multiplied by (times) H2 O.
The electronic structure of Sm(DBM)//3 multiplied by (times) H//2O (DBM EQUVLNT dibenzoylmethanate or 1,3-diphenyl-1,3-propanedionate) has been investigated using absorption and emission spectroscopy of single-crystal and polycrystalline samples in the visible and near IR at 5 K and above. The experimental energies and polarized intensities of the transitions arising from the **6H//5/////2 yields **6F//1/////2//,//3/////2//,//5/////2//,//7/////2//, //9/////2 yields **4G//5/////2//,//7/////2 and **4F//3/// //2 absorption regions and the **6H//5/////2//,//7/////2//,//9/////2 implied by **4G//5/////2 regions in emission have been fitted to C//3 crystal field parameters. However, evidence for slight distortion from exact C//3 symmetry is observed at lower temperatures.
