傅立葉轉換紅外光譜 (Fourier-transform infrared spectroscopy (FTIR)) 是一種用來獲得固體, 液體或氣體的紅外线吸收光譜和放射光譜的技術。傅立葉轉換紅外光譜儀同時收集一個大範圍範圍內的光譜數據。這給予了在小範圍波長內測量強度的色散光譜儀一個顯著的優勢。FTIR已經能夠做出色散型紅外光譜,但使用的並不普遍(除了有時候在近紅外),開啟了紅外光譜新的應用。傅立葉轉換紅外 … 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.
