You have been asked to characterize benzoic anhydride by IR spectroscopy. Unfortunately, your laboratory does not have an instrument equipped with an ATR probe. Choose a technique that could be used to prepare the sample (e.g., neat liquid, solution cell, mull, thin film, solid pellet, etc.) Why did you choose this preparation method? Give a detailed procedure for how you would prepare your sample for analysis. Also list all the spectra you would need to collect in order to complete the characterization.

Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.
