virtual unsigned int GetHyb() const
Return the ``hybridization'' of an atom. The set of unsigned integer
values for this property are defined in the namespace
OEHybridization. The default value is zero,
OEHybridization::Unknown. The ``hybridization'' property may be
set with the OEAtomBase::SetHyb method. Hybridizations may also
be set on a molecule using the function OEAssignHybridization.
The hybridization property of an atom is a stored, not a computed, property.
To calculate a reasonable hybridization of an atom from connectivity, use
the function OEGetHybridization.
