Energetics and Dipole Moment of Transition Metal Monoxides by Quantum   Monte Carlo
  The transition metal-oxygen bond appears very prominently throughout chemistry and solid-state physics. Many materials, from biomolecules to ferroelectrics to the components of supernova remnants contain this bond in some form. Many of these materials' properties depend strongly on fine details of the TM-O bond, which makes accurate calculations of their properties very challenging. Here we report on highly accurate first principles calculations of the properties of TM monoxide molecules within fixed-node Diffusion Monte Carlo and Reptation Monte Carlo.
