Fourier transform infrared spectroscopy (FTIR) [1] 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.

2023年7月8日 · FTIR spectroscopy investigates the interactions between matter and electromagnetic radiation, which appear as a spectrum. FTIR spectrum analysis has enabled the diagnosis of various organ diseases as well as the quantification of various biomolecules such as proteins, nucleic acids, and lipids.

2023年4月10日 · FTIR spectrometers (Fourier Transform Infrared Spectrometer) are widely used in organic synthesis, polymer science, petrochemical engineering, pharmaceutical industry and food analysis.

2024年5月29日 · A Fourier Transform Infrared Spectrometer (FTIR) is a based on the interferometer. The interferometer in an FTIR works on the same principles as the one used in the Michelson–Morley experiment. The Michelson–Morley showed that the speed of light is the same in all directions; a key finding supporting special relativity.

Infrared, or IR, spectroscopy is a chemical analysis technique that takes advantage of the interaction between infrared light and matter. Infrared light is part of the electromagnetic spectrum between visible light and microwaves, with wavelengths ranging from 780 nm to 1 mm.

FTIR Spectroscopy, Fourier-transform infrared spectroscopy, is concerned with the vibration of molecules. Each functional group has its own discrete vibrational energy which can be used to identify a molecule through the combination of all of the functional groups.

Introduction to Modern FTIR Spectroscopy 1.1 Principles of FTIR: The Michelson Interferometer Invented more than one hundred years ago, the two-beam Michelson interferometer 1 is still the heart of most modern Fourier transform infrared (FTIR) spectrometers. It consists of a fixed mirror, a moving mirror and a beamsplitter, as illustrated in
