sc::MolecularFrequencies::MolecularFrequencies(constRef<KeyVal>&)
       The KeyVal constructor.

       mole
           A MolecularEnergy object. If this is not given then molecule must be given.

       molecule
           A Molecule object. If this is not given then mole must be given.

       point_group
           A  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  $C_1$  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.

       debug
           An integer which, if nonzero, will cause extra output.

       displacement
           The amount that coordinates will be displaced. The default is 0.001.

       The MolecularFrequencies class is used to compute the molecular frequencies and thermodynamic
       information.

doublesc::MolecularFrequencies::freq(intirrep,inti)const[inline]
       Returns the frequency, given the irrep and the index. compute_frequencies must be called first.

   intsc::MolecularFrequencies::nfreq(intirrep)const[inline]
       Returns the number of modes in an irrep. compute_frequencies must be called first.

   voidsc::MolecularFrequencies::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::SavableState.

       and thermodynamic information.

       #include <molfreq.h>

       Inherits sc::SavableState.
