    This one came up in google :P

    Hard to come up with a structural formula from an empirical formula, thats why there are so many chemical analysis methods like NMR/MS.

    Double bonds and rings behave differently in spectroscopic analysis, so that would reveal more.

    I tried to guess the structure by trial and error heh, knowing some of the bonding rules, but i failed and consulted google, then kicked myself for not remembering the epoxy Oxy type bond.

    Maybe there are other structures also, consult a chemical catalogue or database.
