In the first part of this experiment, UV-Vis spectra will be recorded for several, simple aromatic molecules in toluene solution. Beer-Lambert plots will be constructed for each aromatic spices and the

molar extinction coefficient determined. In the second part of the experiment, unknown samples will be investigated. Given the information derived in part one, UV-Vis spectroscopy will be used qualitatively to identify the species, and then quantitatively to determine the amount of each component present in the unknown sample.
