Detailed Description
The MolecularFrequencies class is used to compute the molecular frequencies and thermodynamic information.
Constructor & Destructor Documentation
◆ MolecularFrequencies()
The KeyVal constructor.
moleculeA Molecule object. There is no default.
point_groupA PointGroup object. This is the point group used to compute the finite displacements. Since some MolecularEnergy objects cannot handle changes in the molecule's point group, the molecule must be given
symmetry for frequency calculations. In this case, the point_group keyword can be given to reduce number of the displacements needed to compute the frequencies. If this is not given then the point group of the molecule is used.debugAn integer which, if nonzero, will cause extra output.
Member Function Documentation
◆ freq()
|
inline |
Returns the frequency, given the irrep and the index.
compute_frequencies must be called first.
◆ nfreq()
|
inline |
Returns the number of modes in an irrep.
compute_frequencies must be called first.
◆ save_data_state()
|
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::SavableState.
