What is the absorption wavelength of CO2?

15 μm
It has a long lifetime in Earth’s atmosphere. Carbon dioxide strongly absorbs energy with a wavelength of 15 μm (micrometers). This makes carbon dioxide a good absorber of wavelengths falling in the infrared radiation region of the spectrum.

Does CO2 absorb UV radiation?

The wavelengths of CO2 absorption are larger than 2000 nanometers, i.e larger than microns. UV is order of 0.1micron . It may be possible if one is lenient with the limits of definition that some ultraviolet absorption by CO2 may happen, but should not be significant.

How does CO2 absorb IR radiation?

Molecules of carbon dioxide (CO2) can absorb energy from infrared (IR) radiation. The energy from the photon causes the CO2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon.

When a photon is absorbed by a molecule What happens to the photon?

Thus, UC processes are different from concerted multiphoton processes where the photon absorptions occur simultaneously. Figure 1. Principal upconversion (UC) processes: (a) excited-state absorption, (b) energy-transfer UC, and (c) photon avalanche.

What is CO2 absorption?

Absorption of CO2 with ammonia is a technique used to reduce emissions of carbon dioxide to the atmosphere created by fossil-fired power plants. The absorption efficiency of CO2 ranged from a few percent in the experiment with water to up to 7\% with potassium carbonate solution.

What kind of radiation is absorbed by CO2?

infrared
Carbon dioxide acts as a sort of gatekeeper: it allows visible light to pass right by but will absorb infrared (heat) energy. The key to understanding how it does this is a concept called resonance.

What happens to an absorbed photon?

The simplest answer is that when a photon is absorbed by an electron, it is completely destroyed. All its energy is imparted to the electron, which instantly jumps to a new energy level. The electron in the high energy level is instantly converted into a lower energy-level electron and a photon.

How much energy can CO2 absorb?

In fact already 95\% of the radiant energy is absorbed by CO2 at pre-industrial levels leaving a maximum of just 5\% for any increase you like.
