New nonrelativistic and scalar-relativistic pseudopotentials for the second- and third-row transition metals have been developed. These improved Model Core Potentials were used in calculations for a variety of transition metal complexes to test their ability to reproduce experimental structures and vibrational frequencies.
We have recently developed new nonrelativistic and scalar-relativistic pseudopotentials for the first-row transition metal and several main-group elements. These improved Model Core Potentials were tested on a variety of transition metal complexes to determine their accuracy in reproducing electronic structures, bond lengths, and harmonic vibrational(More)
Interactions between the heavier Group 2 metals (Ca, Sr, and Ba) and helium were studied using the well-tempered model core potential method. Accurate pair potentials, calculated at the coupled-cluster level of theory with very large basis sets, were used in bound state calculations. Three bound rovibrational states were found for each complex. The(More)
