Detailed Description

The IrreducibleRepresentation class provides information associated with a particular irreducible representation of a point group.

This includes the Mulliken symbol for the irrep, the degeneracy of the irrep, the characters which represent the irrep, and the number of translations and rotations in the irrep. The order of the point group is also provided (this is equal to the number of characters in an irrep).

Constructor & Destructor Documentation

IrreducibleRepresentation::IrreducibleRepresentation ( int, int, const char * )

This constructor takes as arguments the order of the point group, the degeneracy of the irrep, and the Mulliken symbol of the irrep. The Mulliken symbol is copied internally.

---

Member Function Documentation

void IrreducibleRepresentation::print ( std::ostream & = ExEnv::out() ) const

This prints the irrep to the given file, or stdout if none is given. The second argument is an optional string of spaces to offset by.
