I think I have figured out the IR spectrum for benzophenone. Would it be that the sharp peak in the middle (1700 cm^-1) is for the ketone and the little peaks pass 2900 cm^-1 rang are the sp2/sp3 carbons from the benzene rings?
Also, I have an H-NMR spectrum for the same compound and I know there are only three peaks because the compound is symmetrical. But I am confused on how to determine the J values for each hydrogen.
Can someone kindly assist?
