The evaluation of stoichiometry expressions is case sensitive. In order to avoid ambiguity, use upper case for the first character of element symbols, and lower case for the second character (if any). The way MossWinn resolves ambiguous cases is detailed here.
Number of atoms in molecular formulas can be written directly after the corresponding chemical symbols as usual.
A separate unit of atomic groups can be formed by the means of parentheses or square brackets. The number of units in the molecular formula can be given by a number written directly after the closing parenthesis or square bracket as usual.
Parentheses and square brackets can be nested arbitrarily.
Chemical abbreviations of molecular units can be used between curly brackets. Abbreviations recognized by MossWinn are written with bold characters when the stoichiometry is displayed. Visit this page for the current list of abbreviations that can be used.
Multiplication sign can be used to denote, e.g., hydrous compounds.
Multiplicators can also be written directly before molecular units. The scope of multiplication includes the largest possible molecular unit directly following the multiplicator.
The multiplication sign * terminates the scope of the opening multiplicator 2.
Parentheses can be used to ensure the scope of multiplicators.
The scope of multiplication includes the largest possible molecular unit directly following the multiplicator.
Parentheses can be used to restrict the scope of multiplicators.
Fractions can also be used instead of decimal numbers.
Symbols denoting unknown quantities can be written between double quotes.
HTML-style formatting elements can be used to format any text between double quotes. Use the pairs <i></i> for italic, <b></b> for bold, <u></u> for underline, <sub></sub> for subscript and <sup></sup> for superscript text style.
HTML codes can be used between double quotes to display greek letters in stoichiometry formulas (e.g. α β for α β).
Mass number may be used before the symbol of Mossbauer nuclide in order to emphasize isotopic enrichment. Write a space before the mass number in order to separate it from the preceding quantity. Question marks can be used to denote uncertain quantities.
Fe2(SO4)3 + 2FeCl3
Fe2(SO4)3 + (FeCl3)2
Mixtures can be denoted with + signs written between separate components.
La1/3Sr2/3FeO3"<sub>-<i>y</i></sub> (<i>y</i> < 0.1)"
La1/3Sr2/3FeO3-y (y < 0.1)
A high variety of stoichiometry expressions can be formed by the combination of the syntactic elements.
