The molecular structure of hesperidin was explored. The infrared (MIR) spectroscopy experiments (including one-dimensional MIR spectroscopy, derivative MIR spectroscopy, and deconvolution MIR spectroscopy) on the molecular structure of hesperidin were conducted. The results showed that the infrared absorption modes of the molecular structure of hesperidin include: the stretching vibration mode of the aromatic C-H functional group of hesperidin molecule (ν■), the asymmetric stretching vibration mode of the CH3 functional group of hesperidin molecule (ν■), the asymmetric stretching vibration mode of the CH2 functional group of hesperidin molecule (ν■), the symmetric stretching vibration mode of the CH3 functional group of hesperidin molecule (ν■), the symmetric stretching vibration mode of the CH2 functional group of hesperidin molecule (ν■), hesperidin molecule C=O functional group stretching vibration mode (ν■), hesperidin molecule aryl C=C functional group stretching vibration mode (ν■), hesperidin molecule CH2 functional group bending vibration mode (δ■), asymmetric bending vibration mode of CH3 functional group of hesperidin molecule (δ■), symmetric bending vibration mode of CH3 functional group of hesperidin molecule (δ■), and in-plane rocking vibration mode of CH2 functional group of hesperidin molecule (ρ■).The spectral resolution of deconvoluted MIR spectra of hesperidin molecular structure is superior to one-dimensional MIR spectra and derivative MIR spectra. MIR spectroscopy can quickly conduct molecular structure research on hesperidin.
