You can certainly try:http://sdbs.db.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi; but then, it would only indicate functional group or potential identities, but certainly not for exact molecular structure/ chemical formulae! Thanks, Biswa
BIORAD has database / library for IR Spectrum identification. It will identify the functional groups and also give a library match for the compound. You can contact Biorad directly for more information.
