SavableState & operator= (const SavableState &)
void save_state (StateOut &)
Save the state of the object as specified by the StateOut object. void save_object_state (StateOut &)

This returns the unique pointer to the ClassDesc corresponding to the given type_info object. const char * class_name () const
Return the name of the object's exact type. int class_version () const
Return the version of the class. virtual void print (std::ostream &=ExEnv::out0()) const

Decrement the reference count and return the new count. int managed () const
void unmanage ()

Static Public Member Functions inherited from sc::SavableState
static void save_state (SavableState *s, StateOut &)
static SavableState * restore_state (StateIn &si)
Restores objects saved with save_state. static SavableState * key_restore_state (StateIn &si, const char *keyword)
Like restore_state, but keyword is used to override values while restoring. static SavableState * dir_restore_state (StateIn &si, const char *objectname, const char *keyword=0)

Protected Member Functions inherited from sc::SavableState
SavableState (const SavableState &)
SavableState (StateIn &)
Each derived class StateIn CTOR handles the restore corresponding to calling save_object_state, save_vbase_state, and save_data_state listed above.

sc::MolecularFrequencies::MolecularFrequencies (const Ref< 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.

double sc::MolecularFrequencies::freq (int irrep, int i) const [inline]

Returns the frequency, given the irrep and the index. compute_frequencies must be called first.

int sc::MolecularFrequencies::nfreq (int irrep) const [inline]

Returns the number of modes in an irrep. compute_frequencies must be called first.

void sc::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.
