Fourier transform infrared spectroscopy is a technique employed to generate an infrared spectrum reflecting the absorption or emission of a solid, liquid, or gas sample. This analytical method finds extensive use, particularly for identifying polymers and organic compounds. Through FTIR spectroscopy, an ordered spectrum was produced, facilitating the identification or quantification of the analyzed sample due to distinct molecular infrared fingerprints. In this study, FTIR spectroscopy was employed to validate the reaction′s success by comparing the spectra of the unmodified substrate with those of the BiB substrate and the PNIPAM substrate.
