INFRARED SPECTROSCOPIC ANALYSIS OF THE SYNTHESIZED ORGANOSILICON OLIGOMER
Abstract
This study presents the infrared spectroscopic analysis of a synthesized organosilicon oligomer obtained on the basis of phenol–formaldehyde and orthosilicic acid. The IR spectrum was recorded in the 400–4000 cm⁻¹ region using a Shimadzu IRTracer–100 spectrometer with KBr pellet technique. Characteristic absorption bands were identified, including O–H stretching at 3336 cm⁻¹, CH₂ vibrations at 1479 cm⁻¹, C–O stretching at 1267 cm⁻¹, and aromatic C–H absorptions in the 759–991 cm⁻¹ region. Additionally, the presence of Si–O and C–O bond vibrations confirmed the successful formation of new organosilicon linkages. Comparative analysis with reference spectra verified the structural integrity of the synthesized compound. The findings demonstrate that infrared spectroscopy is a reliable tool for structural identification, functional group analysis, and confirmation of newly synthesized organosilicon compounds.
