The molecules listed below were detected through astronomical spectroscopy. Their spectral features arise because molecules either absorb or emit a photon of light when they transition between two molecular energy levels. The energy (and thus the wavelength) of the photon matches the energy difference between the levels involved. Molecular electronic transitions occur when one of the molecule's electrons moves between molecular orbitals, producing a spectral line in … WitrynaExhaled volatile organic compounds (VOCs) analysis through electronic nose is a promising approach in the study of lung disease. This technique provides a “fingerprint” of the exhaled breath (dubbed “breathprint”), obtained by interaction occurring between VOCs and a sensor array, which has been shown to discriminate COPD patients from ...

"WitrynaThe compounds in solid, liquid or gaseous states which contain carbon in their molecule are known as organic compounds. There are a large number of organic compounds and therefore a proper systematic classification was required. Organic compounds can be broadly classified as acyclic (open chain) or cyclic (closed chain). " - Organic compounds in space
