WebThe IR spectrum plays an important role and provides valuable information related to the functional groups in pentacyclic triterpenoids. IR spectra of triterpenoids have two characteristically regions. Absorption bands in the region 3500–3650 and 2650–3350 cm − 1 are due to OH stretching and –CH stretching, respectively. WebCh13 - Sample IR spectra. Sample IR Spectra : heteroatom functional groups. By looking at IR spectra that contain known functional groups and comparing and contrasting them with other IR spectra, one can develop the skills required to be able to "interpret" an "unknown" IR spectra. Remember that for an organic chemist, the primary role of IR is ... WebThe absorption bands in IR spectra have different intensities that can usually be referred to as strong (s), medium (m), weak (w), broad and sharp. The intensity of an absorption band depends on the polarity of the bond, and a bond with higher polarity will show a more intense absorption band. chinese restaurant on west napoleon
