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:. total_charge This integer 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

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.
