## Member Function Documentation

double sc::OSSSCF::alpha_occupation | ( | int | irrep,
|  | int | vectornum |
| ) |  |  | `[virtual]`

Returns the alpha occupation.

The irreducible representation and the vector number within that representation are given as arguments.

Reimplemented from sc::OneBodyWavefunction.

double sc::OSSSCF::beta_occupation | ( | int | irrep,
|  | int | vectornum |
| ) |  |  | `[virtual]`

Returns the beta occupation.

The irreducible representation and the vector number within that representation are given as arguments.

Reimplemented from sc::OneBodyWavefunction.

double sc::OSSSCF::occupation | ( | int | irrep,
|  | int | vectornum |
| ) |  |  | `[virtual]`

Returns the occupation.

The irreducible representation and the vector number within that representation are given as arguments.

Implements sc::OneBodyWavefunction.

void sc::OSSSCF::save_data_state | ( | StateOut & |  | ) | `[virtual]`

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

This must be implemented by the derived class if the class has data.

Reimplemented from sc::SCF.

Reimplemented in sc::OSSHF.

void sc::OSSSCF::symmetry_changed | ( |  | ) | `[virtual]`

Call this if you have changed the molecular symmetry of the molecule contained by this MolecularEnergy.

Reimplemented from sc::SCF.
