Ir spectra groups

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.
