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. WebIt also means that the product could be a meso hydrobenzoin. Based on the IR spectrum, we concluded that the identity of our product was meso hydrobenzoin. This was proven by the O-H alcohol bond at 3372 cm-1 and 3306 cm-1. The double O-H bond is yielding two alcohol groups in the product. This proves that our product is meso hydrobenzoin. green printing software
