Keeping with the theme of autumn, one of Dr. Danahy’s favorite molecules is caffeic acid due to its presence in pumpkins. This structure serves as an antioxidant and is one of many found within pumpkins. Despite its name, it bears no resemblance to caffeine. Answer the following questions about caffeic acid. The carbonyl stretch for caffeic acid is unusually low for a carboxylic acid at 1646 cm-1. For reference, the carbonyl stretch for propanoic acid is 1716 cm-1. Explain why the carbonyl stretch occurs at a lower wavenumber for caffeic acid.
Im having a hard time distinguishing peaks on an IR spectrum. Theyre often very crowded, and i dont know if broad peaks get combined with sharp peaks. On this IR spectrum, it seems there is a broad range, medium strength band extending from 4000 to (about) 2000 cm-1, with several sharp peaks on top of that range. Does this mean that there is a carboxylic acid O-H present as well as the other bonds determined by the sharp peaks?

The beer-lambert law is A = εlc, where A is the absorbance, ε is the molar extinction coefficient, l is the path lengh in cm and C is the concentration. The beer lambert law can be expressed in the form of y=mx + b, where A is y, and C is x.What is b and how is it used to calculate the final absorbance?
