Abstract: Recent advances in the high sensitivity spectroscopy have made it possible, in combination with accuratetheoretical predictions, to observe for the first time very weak electric quadrupole transitions in a polarpolyatomic molecule of water. Here we present accurate theoretical predictions of the complete quadrupole ro-vibrational spectrum of a non-polar molecule CO$_2$ , important in atmospheric and astrophysical applications.Our predictions are validated by recent cavity enhanced absorption spectroscopy measurements and are usedto assign few weak features in the recent ExoMars ACS MIR spectroscopic observations of the martianatmosphere. Predicted quadrupole transitions appear in some of the mid-infrared CO$_2$ and water vaportransparency regions, making them important for detection and characterization of the minor absorbers inwater- and CO$_2$-rich environments, such as present in the atmospheres of Earth, Venus and Mars.
