Description
An analysis technique used to obtain an absorption or emission spectrum of vibrational changes in chemical bonds. A Fourier-transform infrared (FTIR) spectrometer simultaneously collects high-resolution spectral data over a wide spectral range, typically 4000-600 cm-1 (wavenumbers). The vibrational changes that occur in chemical functional groups are unique and reproducible. The combination of these interactions with the infrared beam, represented as a spectrum, produce a unique pattern for each class of material. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time. in the components in a solid, liquid, or gas
