Title: Valence : A Massively Parallel Implementation of the Variational Subspace Valence Bond Method

Journal Article · · Journal of Computational Chemistry
DOI:https://doi.org/10.1002/jcc.25818· OSTI ID:1510723

This work describes the software package, Valence , for the calculation of molecular energies using the variational subspace valence bond (VSVB) method. VSVB is an ab initio electronic structure method based on nonorthogonal orbitals. Important features of practical value include high parallel scalability, wave functions that can be constructed automatically by combining orbitals from previous calculations, and ground and excited states that can be modeled with a single configuration or determinant. The open‐source software package includes tools to generate wave functions, a database of generic orbitals, example input files, and a library build intended for integration with other packages. We also describe the interface to an external software package, enabling the computation of optimized molecular geometries and vibrational frequencies. © 2019 Wiley Periodicals, Inc.
