WebThe IR spectrum, shown in figure 3, shows a C-H sp 3 stretch at 3000-2800 cm-1 and a C=O stretch at ~1736 cm-1, which are both present in camphor. The IR spectrum also shows an impurity stretch at 3500-3300 cm-1. Because the stretch is similar to an O-H stretch, this impurity most likely came from water or ether still present in the final product. http://www.mendelset.com/articles/686/infrared_absorbance_spectroscopy_ir
