Abstract
The MCD of $U(BH_{4})_{4}$ doped into $Hf(BH_{4})_{4}$ has been measured in the visible and near infrared regions at liquid helium temperatures. Several distinctive A-terms were found to correspond to previously assigned electric dipole origins of $(5f)^{2}$ in a $T_{d}$ site. Their signs and lack of temperature dependence are used to confirm the $E(^{3}H_{4})$ ground state. The symmetries of several excited states are further confirmed using moment analysis.
