static_job(
    atoms: Atoms,
    charge: int = 0,
    spin_multiplicity: int = 1,
    method: str = "wb97x-v",
    basis: str = "def2-tzvp",

        SourceDirectory
        | dict[SourceDirectory, Filenames]
        | None
    ) = None,
    **calc_kwargs
) -> RunSchema

Function to carry out a single-point calculation.

Parameters:

  • atoms (Atoms) –

    Atoms object

  • charge (int, default: 0 ) –

    Charge of the system.

  • spin_multiplicity (int, default: 1 ) –

    Multiplicity of the system.

  • method (str, default: 'wb97x-v' ) –

    The level of theory to use.

  • basis (str, default: 'def2-tzvp' ) –

    Basis set

  • copy_files (SourceDirectory | dict[SourceDirectory, Filenames] | None, default: None ) –

    Files to copy (and decompress) from source to the runtime directory.

  • **calc_kwargs –

    Custom kwargs for the Psi4 calculator. Set a value to quacc.Remove to remove a pre-existing key entirely. For a list of available keys, refer to the ase.calculators.psi4.Psi4 calculator.
