3.1.16 GetIsotope

virtual unsigned int GetIsotope() const

Return the isotopic mass of an atom. The default value is zero, meaning that the atom isn't a specific single isotope, but a composition of isotopes in their naturally occurring abundances. A non-zero value indicates that the atom is a specific isotope. The ``isotopic mass'' property may be set using the OEAtomBase::SetIsotope method.
