WebThe first way was done by an IR spectroscopy, shown in figure 4. The IR spectrum shows a C-H sp3 stretch at 3000-2800 cm-1 and an O-H stretch at 35000-3200 cm-1. Both of these bonds are present in isoborneol and borneol, indicating that they are not impurity stretches. Another analysis of the products was done by H-NMR spectroscopy, shown in ... WebNov 19, 2015 · After we have obtained our spectra we can see that the two portions of the particle provide very different infrared spectra. If we take a closer look we can confirm that no peaks from one spectrum are present in the other. So the two components were cleanly separated. So we can go ahead and start working to identify each part.
