subscripts and superscripts

For normal editing purposes, I use vim and it works great. But once in
a while, I want to use subscripts and superscripts. For example, while
writing chemical equations I would like to see O with a subscript 2 to
represent the Oxygen molecule. Without using heavy weight stuff such
as Latex, could I somehow make vim/gvim show subscripts and
superscripts?

thanks
