Ab Initio Calculation of U ($BH_{4})_{4}$

Author Institution: Department of Chemical Physics, The Ohio State UniversitySCF calculations with relativistic core potential and double zeta Gaussian basis SCL, followed by spin-orbit Cl calculations, were carried out on U($BH_{4})_{4}$. The ground state is found to be B state in double group notation, in agreement with experiments. The low lying $f - >f$ transitions are calculated and results are compared with experiments and ligand field theory assignments
