# LOCAL_WEAKP

> Desired treatment of “weak pairs” in the local-CCSD method. A value of `NEGLECT` ignores weak pairs entirely. A value of `NONE` treats weak pairs in the same manner as strong pairs. A value of MP2 uses second-order perturbation theory to correct the local-CCSD energy computed with weak pairs ignored.

> - Type: string
> - Possible Values: NONE, MP2, NEGLECT
> - Default: NONE
