    the structure had to add up to 148. ATR-IR suggested the presence of an aromatic ring‚ alkene group and carbonyl group. CNMR showed the presence of an aromatic ring‚ carbonyl group and a methyl group. HNMR showed the presence of an aromatic ring‚ alkene group and carbonyl. Using the rule of 13 and the adjustment for oxygen‚ the predicted structure of the anise oil was C10H12O with 5 degrees of unsaturation. Since the aromatic ring is 4 degrees of unsaturation by itself‚ the last degree of unsaturation
