Detailed Description

The CLSCF class is a base for classes implementing a self-consistent procedure for closed-shell molecules.

Constructor & Destructor Documentation

sc::CLSCF::CLSCF (const Ref< KeyVal > &)

The KeyVal constructor:. .IP "total_charge" 1c This floating point number gives the total charge of the molecule. The default is 0.

docc: This vector of integers gives the total number of doubly occupied orbitals of each irreducible representation. By default, this will be chosen to make the molecule uncharged and the electrons will be distributed among the irreducible representations according to the orbital energies.

Member Function Documentation

RefSymmSCMatrix sc::CLSCF::effective_fock () [virtual]

Returns closed-shell Fock matrix in MO basis (including XC contribution for KS DFT).

Implements sc::SCF.

Reimplemented in sc::CLKS.

RefSymmSCMatrix sc::CLSCF::fock (int i) [virtual]

Returns closed-shell Fock matrix in AO basis (excluding XC contribution in KS DFT). Use effective_fock() if you want the full KS Fock matrix. Argument i must be 0.

Implements sc::SCF.

double sc::CLSCF::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::CLSCF::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::CLKS, and sc::CLHF.

void sc::CLSCF::symmetry_changed () [virtual]

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