CO2: Fundamental rotational frequency is 72 GHz. The EM spectrum of rotational lines only exists as lines in a vibrational-rotational spectrum. CO2 has no pure rotational EM spectrum. The pure rotational energy levels of the molecule exist but they don’t interact with EM radiation.

Compare this to the rotational and translational energies in your CO2 and H2O vibrational frequency output. 2. Methanogenesis is thought to be one of the more primitive metabolic strategies for early life, and is still used by bacteria in anaerobic environments: CO2 + 4H2 ( CH4 + 2H2O

Conventional CO2 lasers operated at atmospheric pressure lack sufficient bandwidth to amplify picosecond pulses. For example, on the 10P vibrational-roatational manifold, the gain spectrum at 1atm consists of discrete rotational transitions separated by 55GHz each having a bandwidth of ~3.7GHz. This bandwidth limits the amplification to ~3ns ...

The frequency of the absorbed radiation is related to the energy of the transition by Planck's law: ΔE = hc/ . ... In order for a particular vibrational mode to directly absorb infrared electromagnetic radiation, the vibrational motion associated with that mode must produce a change in the dipole moment of the molecule ... Consider the CO2 ...

Other factors will also influence the intensity and shape of the absorption. However, when the frequency of the electromagnetic radiation equals the vibrational frequency of a molecule, absorption of light does occur and this leads to an infrared spectrum that is characteristic of the …

Since the energies involved with the bending will be different for each kind of bond, each different bond will absorb a different frequency of infra-red radiation in order to make this jump from one state to a higher one. Vibrational modes of CO2 vs SO2 CO2 SO2

At exactly the right frequency, the radiation would be absorbed, going into vibrational energy, and the transmission drops from 100%. The figure below shows what is observed. The infrared spectrum, that is the amount of light transmitted at different wavelengths, of carbon dioxide is displayed.
