    • createAnalysis

      public static ElementalAnalysis createAnalysis(String formula)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Constructs an elemental analysis from molecular formula.

      Multiple fragments with fractional stoichiometric coefficients are supported: CH3O.0.5Na.1.5H2O, NaCl.1.5H2O, AlCl3.1.5H2O
      If the molecular formula contains any unspecified symbol (e.g. R, Pol) the analysis do not take into consideration these symbols. The analysis returns the same result for formulas either with or without these symbols.

      Parameters:
      formula - molecular formula, e.g. C3H8NO2, Al2(CO3)3.2H2O
      Returns:
      an ElementalAnalysis instance
      Throws:
      com.chemaxon.calculations.elemanal.formula.tree.InvalidFormulaException - if the parser cannot parse the formula string
