Elemental Analysis

    AtomCount

    Returns the number of atoms in the molecule, including hydrogens. The number of atoms having different types can be counted as well if the atomic number of an atom is specified.

    DotDisconnectedFormula

    Returns the chemical formula of the molecules, separating fragment formulas by dots, for example, salts, counterions, and solvent molecules are present.

    DotDisconnectedIsotopeFormula

    Returns the chemical formula of the molecule separating fragment formulas by dots and listing isotopes separately.

    ExactMass

    Returns the monoisotopic mass calculated from the weights of the most abundant natural isotopes of the elements.

    IsotopeFormula

    Returns the chemical formula of the molecule listing isotopes separately according to the Hill system.

    Mass

    Returns the average molecular mass calculated from the standard atomic weights.

    MolFormula

    Returns the chemical formula of the molecule according to the Hill system: the number of carbon atoms is indicated first, the number of hydrogen atoms next (including deuterium and tritium when using D and T symbols), and then the number of all other chemical elements subsequently, in alphabetical order. When the formula contains no carbon, all the elements, including hydrogen, are listed alphabetically. Formulas for polymers can also be calculated with these functions.
