Abstract

Reabsorption of the emission from Tb3+ in 4f 8 → 4f 75d transitions is examined for coordination compounds of the ion with \-diketones. The energy levels are calculated by MOLCAO methods. The Tb3+ (4f 75d) is assumed to interact only with adjacent oxygen atoms; the effects of the other atoms are allowed for via a preliminary calculation of the charge distribution in the \-diketone anions. The energy spectrum is deduced as a function of the charge on the oxygen atoms in the \-diketone anion.
