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 … Meer weergeven 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, … Meer weergeven In a Michelson interferometer adapted for FTIR, light from the polychromatic infrared source, approximately a black-body radiator, is collimated and directed to a beam splitter. … Meer weergeven There are three principal advantages for an FT spectrometer compared to a scanning (dispersive) spectrometer. 1. The multiplex or Fellgett's advantage. This arises from the fact that information from all wavelengths is collected simultaneously. … Meer weergeven IR sources FTIR spectrometers are mostly used for measurements in the mid and near IR regions. For … Meer weergeven 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 from 2.5 μm to 15 μm (wavenumber range 4,000 cm to 660 cm ). The lower … Meer weergeven 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.
