Procedure-Part 1: Obtain an infrared spectrum for one of the following known organic liquids: oleic acid (K1), butyl methyl ether (K2), or cyclo hexanone (K3). Place-20 pL of HO sample on the diamond crystal. Analyze your spectrum K1 and complete the table below. List five to ten of the most important/prominent peaks in the spectrum; round wavenumber values to the nearest whole number. Note the intensity/shape of each peak using the following descriptors: strong, medium, weak, and broad. Identify if...
