\startluacode

thirddata = thirddata or { }

function thirddata.molecule(text)
     text = string.gsub(text,"_","\\low")
     text = string.gsub(text,"%^","\\high")
     tex.sprint(text)
end

\stopluacode

\def\molecule#1{\ctxlua{thirddata.molecule('#1')}}

\starttext
\molecule{H_2SO_4}
\molecule{H_2^+}
\stoptext
