WebThe strength (intensity) of an absorption in the infrared is dependent on the change of dipole moment occurring during the vibration. If there is no change in dipole moment then the … WebMolecules of carbon dioxide (CO 2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO 2 absorbing an incoming infrared photon (yellow arrows). The energy from the photon causes the CO 2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon.

Carbon Dioxide Absorbs and Re-emits Infrared Radiation

WebGreenhouse gases are gases in the Earth’s atmosphere that can absorb and emit radiation, primarily infrared radiation. The greenhouse gas that interacts with radiation across the largest number of wavelengths is water vapor (H 2 O), which interacts strongly with the atmosphere, especially in the longer wavelength portion of the spectrum.
