Module contents¶

pyscf.pbc.gto.basis.load(file_or_basis_name, symb, optimize=False)¶

Convert the basis of the given symbol to internal format

Args:

file_or_basis_namestr: Case insensitive basis set name. Special characters will be removed.
symbstr: Atomic symbol, Special characters will be removed.

Examples:

Load DZVP-GTH of carbon

>>> cell = gto.Cell()
>>> cell.basis = {'C': load('gth-dzvp', 'C')}

pyscf.pbc.gto.basis.parse(string, optimize=False)¶

Parse the basis text in CP2K format, return an internal basis format which can be assigned to Cell.basis

Args:: string : Blank linke and the lines of “BASIS SET” and “END” will be ignored

Examples:

>>> cell = gto.Cell()
>>> cell.basis = {'C': gto.basis.parse("""
