#56 Spectroscopy Techniques | Part 3 | FTIR & NMR Spectroscopy | Part 1

Welcome to 'Characterization of Construction Materials' course ! This lecture explains Fourier transform infrared (FTIR) spectroscopy, a widely used technique for analyzing materials. Explore: The advantages of FTIR over traditional dispersive IR spectroscopy, including higher sensitivity and faster data acquisition. The principle of FTIR: using an interferometer to generate an interferogram, which is then mathematically transformed into a spectrum. Interferogram: a time-domain signal representing the interference pattern of light waves. Fourier transform: a mathematical operation converting the time-domain interferogram into a frequency-domain spectrum. Interpreting FTIR spectra: identifying characteristic peaks corresponding to specific molecular vibrations and functional groups.
