How do atmospheric gases absorb radiation?

How do atmospheric gases absorb radiation? How does that process work ?
Atmospheric gases absorb radiation by absorbing photons of various wavelengths in the electromagnetic spectrum. The gases absorb the radiation and convert the energy into heat. This process is known as radiative absorption. Gases such as carbon dioxide and water vapor are particularly effective at absorbing radiation in the infrared portion of the spectrum, while ozone and nitrous oxide absorb radiation in the ultraviolet portion of the spectrum.
