Abstract
The absorption spectrum of a thin film of uranium(III) formate was measured at 4 and 300 K in the 4000–23 000 cm −1 range. The energy levels of U 3+ were assigned and fitted to a semiempirical Hamiltonian representing the combined atomic and crystal-field interactions at the C 3v symmetry site. Ten energy level parameters were varied simultaneously in least-squares adjustments yielding a mean error of 23 cm −1. The analysis enabled the determination of the crystal-field parameters and the assignment of 49 crystal-field levels. The calculated total splitting of the ground level is equal to 520 cm −1. An analysis of the 5f 3→5f 3 band intensities based on the Judd–Ofelt theory is presented.
