Characterize your compounds by IR, UV-VIS and melting point. Be certain to explain, interpret and compare all of your data (including to previously reported values in the primary literature).
You should be able to get the UV-VIS spectrum of at least one of these compounds in 95% ethanol. Make up your solution volumetrically in order to determine the epsilon value. Decomposition in solution can be rapid, so make up your sample at the instrument and work quickly!
