 Gas in scattering media absorption spectroscopy

Gas in the context of scattering media absorption spectroscopy refers to a state of matter in which particles, such as molecules or atoms, exist in a well-dispersed manner with relatively large spaces between them, allowing them to move freely. In spectroscopy, particularly absorption spectroscopy, gases can absorb specific wavelengths of light, leading to characteristic absorption spectra that can be used to identify and quantify the presence of certain substances.
