Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. This confers a significant advantage over a … See more The goal of absorption spectroscopy techniques (FTIR, ultraviolet-visible ("UV-vis") spectroscopy, etc.) is to measure how much light a sample absorbs at each wavelength. The most straightforward way to do this, the … See more The interferogram has to be measured from zero path difference to a maximum length that depends on the resolution required. In practice the scan can be on either side of zero resulting in a double-sided interferogram. Mechanical design limitations may … See more FTIR is a method of measuring infrared absorption and emission spectra. For a discussion of why people measure infrared absorption and emission spectra, i.e. why and how substances absorb and emit infrared light, see the article: Infrared spectroscopy See more The first low-cost spectrophotometer capable of recording an infrared spectrum was the Perkin-Elmer Infracord produced in 1957. This instrument covered the wavelength range … See more In a Michelson interferometer adapted for FTIR, light from the polychromatic infrared source, approximately a black-body radiator, is See more There are three principal advantages for an FT spectrometer compared to a scanning (dispersive) spectrometer. 1. The … See more IR sources FTIR spectrometers are mostly used for measurements in the mid and near IR regions. For the mid-IR region, 2−25 μm (5,000–400 cm ), … See more WebThe GC-IR Interface for Nicolet FTIR spectrometers couples the separation capability of gas chromatography (GC) with the specific identification power of Fourier transform infrared (FTIR).

WebElectromagnetic Spectrum. FTIR spectroscopy takes advantage of how IR light changes the dipole moments in molecules (Fig. 2) that correspond to a specific vibrational energy. Vibrational energy corresponds to two variables: reduced mass (μ) and bond spring constant (k) (Equation 1). For k constant, we can look at C-C, C=C, and C≡C showing an ...
