How infrared spectroscopy used in an industry to find the purity of an ester?

Answer 1

Best Answer - Chosen by Voters

When you use an IR spectroscopy machine, you get a a graph show the amount of energy transmitted by the substance as different wavelengths. If the substance you're testing is pure, the graph will have specific peaks at certain wavelengths. So the graph will have a certain shape for a certain substance. If there are impurities in an ester, you will see peaks in the IR graph that are not in the ester's actual spectroscopy graph, indicating something else in it. If the ester is pure, its IR graph would match that in a reference book.
