There are 25 peaks (28 if you count the solvent) in the 13C NMR spectrum of trifluoroacetylguaiazulene, even though one might expect 16 peaks based on the number of chemically distinct carbons. What accounts for the extra peaks? (and just in case youâre wondering: NO, the extra peaks are not due to impurities) List the chemical shift of all 16 carbons. Note: Peak at 77 is due to CDCl3, peak at 135 is a doublet peak, and peak at 141 is a doublet of doublet.
