Assuming you mean "infix to Reverse Polish", I guess you need something that
will parse mathematical expressions. You might like to check out Happy...
it's a parser generator for Haskell, and you could write your own infix to RPN
program using it. Alternatively, there is a parsing combinator library that's
probably a lot easier to work with, but less general. Both are available at
http://www.haskell.org/libraries/
