The molecular structure of dimethyl silicone oil was explored. The diffuse reflectance mid infrared (MIR) spectroscopy experiments on the molecular structure of dimethyl silicone oil and conducted statistical studies on the infrared absorption frequencies corresponding to its main functional groups were conducted. The results showed that the infrared absorption modes of dimethyl silicone oil molecular structure mainly include: CH3 functional group asymmetric stretching vibration mode (ν■), CH3 functional group symmetric bending vibration mode (δ■), Si-O functional group stretching vibration mode (ν■), Si-C functional group stretching vibration mode (ν■), and CH3 functional group in-plane swinging vibration mode (ρ■). At a temperature of 303 K, the structure corresponding to the dimethyl silicone oil molecule ν■ is the most active, while the structure corresponding to δ■ is relatively stable. Diffuse reflectance MIR spectroscopy can rapidly investigate the molecular structure of dimethyl silicone oil.
