Vibrational spectra of Ocimum basilicum L. seed gum

The vibrational spectra of some components of Ocimum basilicum L. seed gum were investigated. After extracting and purifying the fractions, the mid and far Fourier Transform infrared (FT-IR) spectra of them were recorded. Furthermore, the vibrational wavenumbers obtained in the B3LYP and TPSSh methods of density functional theory (DFT) using 6-311++G** basis set, compared with the corresponding experimental IR spectra, and clearly assigned. The functional groups and the physical properties accompanied with each functional group were discussed according to the assignments. The spectra indicate that some compounds are engaged in hydrogen bonding
