摘要
We present in this paper a systematic investigation of the accuracy of different theoretical approaches to uranyl reduction. All-electron and RECP results are compared at the SCF and different correlated levels, including density functional methods. The comparison is done for geometries and reaction energies. The influence of spin-orbit interaction on energies is also investigated. (C) 1999 Elsevier Science B.V. All rights reserved.
