! EXAM 38. ! Analytic gradients for Model Core Potentials (MCP), ! with a DZP quality basis, for BiCl3. Model Core ! Potentials account for scalar relativity effects, ! and preserve all valence orbital radial nodes. ! ! The latter point stands in contrast to the ! Effective Core Potential (ECP) pseudopotentials. ! ! FINAL RHF E= -116.3966190315, RMS grad= 0.0053955 ! FINAL RHF E= -116.3972798614, RMS grad= 0.0036800 !
