IR is far less expensive the ¹H NMR and a better choice to distinguish molecules when possible. Consider the reaction below. Would IR or NMR be a better choice to distinguish the organic starting material and the product? + HBr Br IR is better because the starting material has a C=C peak around 1600 cm-1 and the product does not. IR is better because the product will have a C-Br peak around 2500 cm1 and the starting material will not. O ¹H NMR is better because these two molecules will not show peaks in IR. O Nether IR nor ¹H NMR can distinguish these molecules, they are too similar.
