WebJun 2, 2024 · For systems with periodic boundary condition , plane wave basis is usually adopted. While for molecular systems, gaussian basis set is normally adopted. For periodic systems, the gaussian basis is transformed from real lattice space to momentum space (or k space) through Bloch function. WebBasis sets are associated with centers by using the tag of a center in a geometry that has either been input by the user or is available elsewhere. Each atom or center with the same tag will have the same basis set. All atoms must have basis functions assigned to them – only dummy centers ( X or Bq) may have no basis functions.
