WebThe NIST Quantitative Infrared Database currently consists of a collection of absorption coefficient spectra of volatile organic compounds. These spectra were measured from primary gas standards prepared and verified at NIST. Spectra are provided in 5 resolutions from 2.00 cm −1 to 0.125 cm −1 using 5 apodization functions. WebIntroduction. Fourier transform infrared (FTIR) spectroscopy is a form of vibrational spectroscopy that is useful in the study of a variety of soil chemical processes. In the mid-infrared (mid-IR) range, vibrations arise from many environmentally important molecules such as organic acids, soil organic matter, mineral phases, and oxyanions.
