Fourier Transform Infra-Red spectroscopy. A method used to measure variations in the ratio of hydrogen chloride and sulphur dioxide gases emitted by the volcano. It ultilised the differing light absorbtions in the infra-red region of the electromagnetic spectrum.
Fourier Transform Infrared Spectroscopy - Technique for obtaining vibrational spectrum of a material. Often used for identifying or fingerprinting materials. Obtained spectra can be compared to reference spectra.
This stands for Fourier Transform Infrared spectroscopy that is an analytical method used for the analysis of organic components. Can be used with phosphate esters to detect some contaminants and to identify degradation byproducts.
Fourier Transform Infrared Spectroscopy. A method of material analysis that employs the mathematical theory of nineteenth century French mathematician, Joseph Fourier, to analyze electron density in order to gauge the location of atoms.
Fourier Transform Infrared: a means of testing for oxygen or carbon levels in the crystal.
Abbreviation for Fourier Transform Infrared Radiometer.
Fourier Transformation Infrared Spectroscopy. An instrumental method of analysis used for qualitative identification of organic and inorganic compounds. The technique can sometimes be used for quantitative analysis of mixtures of materials.
