CO2 Infrared Spectrum Absorption Modes
CO2 (O=C=O) asymmetric stretch and bends. Firefly 8.2.0 DFT B3LYP 6-311++G(d,p) geometry-optimized structure (energy minimum, no imaginary frequencies). C=O bond length = 1.16 Å. Gabedit 2.4.8 visualization. In a classical Newtonian sense, the atoms can be considered small weights on springs (covalent bonds) that vibrate at certain frequencies. The blue arrows represent the direction of atom movement within the molecule.
Carbon dioxide is an atmospheric pollutant, contributing to global warming and a mildly electrophilic acidic oxide, slightly reducing the pH in oceans by forming carbonic acid (CO2(aq) + H2O(l) → H2CO3(aq); reversible equation) which is affecting some aquatic life. There are global efforts to reduce CO2 formation and presence from combustion of fossil fuels and deforestation. The molecule absorbs and re-emits infrared radiation (heat) due to the asymmetric stretching and bending motions (the two asymmetric bending modes occur at the same frequency). There is also symmetric stretching, but is not shown here, as it is not detected in an IR spectrum. The dense atmosphere of Venus is mostly CO2, so has an uninhabitable surface temperature.
