If anyone could help with this it would be greatly appreciated.
I am looking at this spectra
http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi(you have to type in 1-indanone, it wont let me link to the page directly)
i know that 1712 i caused by c=o and that 768 is caused by o substitution on the aromatic ring
now i know that there should be 3 or 4 peaks between 1640 and 1430 for the aromatic ring, but im not sure which one of the 6 bands in that region i should claim are from the aromatic ring. should i just pick the strongest?
-thanks
