Web1. Introduction. Fourier transform infrared (FTIR) spectroscopy is a nondestructive chemical characterization technique that encompasses the wave number range of 12500 cm-1 to 10 cm-1 of the electromagnetic spectrum ().This spectral zone is divided into three regions: near-infrared (12500 cm-1 - 4000 cm-1), mid-infrared (4000 cm-1 - 200 cm-1) …
WebFigure 4. FTIR spectrum of 68 mole % PVOH in the EVOH copolymer. The characteristic PVOH absorbance band was located at 3300 cm-1 and PE absorbance band at 1430 cm-1 From Quantitative Analysis of Polyvinyl … WebFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample.
