basisset(self: psi4.core.JK) → psi4.core.BasisSet

static build(orbital_basis, aux=None, jk_type=None, do_wK=None, memory=None)

Constructs a Psi4 JK object from an input basis.

Parameters:

• orbital_basis (BasisSet) – Orbital basis to use in the JK object.
• aux (BasisSet, optional) – Optional auxiliary basis set for density-fitted tensors. Defaults to the DF_BASIS_SCF if set, otherwise the correspond JKFIT basis to the passed in orbital_basis.
• jk_type (str, optional) – Type of JK object to build (DF, Direct, PK, etc). Defaults to the current global SCF_TYPE option.

Returns:

Uninitialized JK object.

Return type:

JK

Example

jk = psi4.core.JK.build(bas) jk.set_memory(int(5e8)) # 4GB of memory jk.initialize()

…

jk.C_left_add(matirx) jk.compute() jk.C_clear()
