Infrared spectroscopy (IR spectroscopy) … deals with the infrared region of the electromagnetic spectrum, that is, light with a longer wavelength and lower frequency than visible light. It covers a range of techniques, mostly based on absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify and study chemicals. 5, record 1, English, - infrared%20spectrometry

La spectroscopie à infrarouge (spectroscopie IR) est une méthode analytique physique qui fonctionne à l’aide de rayons infrarouges […] La spectroscopie IR permet de saisir la concentration de matière dans les gaz, [les] solides et [les] fluides aussi bien qualitativement que quantitativement. […] la transmission [des ondes infrarouges] est calculée sur base de la longueur d’onde de la lumière. Chaque molécule absorbe la lumière d’une certaine longueur d’onde et est donc facilement identifiable. 4, record 1, French, - spectrom%C3%A9trie%20infrarouge

La espectroscopía de infrarrojos (IR) es una técnica de análisis de sustancias en el estado gaseoso, líquido o sólido, tanto cristalinas como amorfas, mediante su espectro de absorción o reflexión en el rango IR del espectro electromagnético, permitiendo así la identificación de compuestos químicos a través de la determinación de la frecuencia a la que los distintos grupos funcionales presentan bandas de absorción en la región IR. 4, record 1, Spanish, - espectrometr%C3%ADa%20de%20infrarrojos
