Abstract
Normal-coordinate analyses using the eleven zero-order normal-mode frequencies of UO2Cl2– 4, UO2Br2– 4(D4h) and UO2F3– 5(D5h) with up to ten parameters in the Urey–Bradley force-field and modified Urey–Bradley force-field approximations, and a ten-parameter modified-valence force field with several different choices of angle-bending interaction constants have been made. A comparison of the modified-valence force constants in the electronic ground state and the first excited state of UO2Cl2– 4 and in the electronic ground states of the chloro-, bromo- and fluoro-substituted anions is made.
