1. The problem statement, all variables and given/known data Can someone tell what the structure is by looking at the above spectra? Here is spectra: http://i39.tinypic.com/zmjypd.png http://i44.tinypic.com/wkst91.jpg 2. Relevant equations What is the 134 fragment? and what is the structure? 3. The attempt at a solution I see from IR spectrum that I have OH, C-H sp2, C-H sp3, C=C aromatic, C-O groups. I see that I have 91, 134, and 149 fragments. I know that 91 is benzene-ch2+ fragment. I don't know what the 134 or 149 fragments are. I know that 149 is actually the whole structure. Looking at proton and C13 NMR i see that i have OH, benzene, CH3, CH2, CH groups, not sure if i got all of those groups right.
