The \hyphenation command can be used to add extra hyphenation patterns globally to a document. This is useful for special words, that are not present in the general hyphenation patterns.
The above example results in LaTeX being able to optionally hyphenate the two words "chronoamperometric" and "micrographs" at all places where they contain dashes.
I would like to add words such as "chromium(III)" to the hyphenation patterns (as in the example above), but the parentheses cause an error ("Not a letter"). How can words with parentheses be automatically hyphenated?
Ideally, I would also like to be able to specify to LaTeX that for any word that is already in the hyphenation rules, continue to hyphenate it also if it is followed by something within parentheses, and add the possibility to hyphenate between the word and the left parenthesis.
