Abstract

The frequency and intensity of IR absorption bands of female sex hormone, 17?-estradiol, are calculated and assigned using density functional theory with the B3LYP/6-31G** approach. For a big number of bands such assignment is made for the first time. The frequencies and normal modes of vibrations are predicted in the low-frequency region of the IR spectrum.
