Infrared light is ‘heat radiation’ transmitted as photons (photonic energy). This is a quantum level function that is, also, true of visible light and all of the other frequencies of the electromagnetic spectrum emitted by suns.
When the quantum wave function of a photon is blocked, it collapses and energy is released into whatever interfered with it.
Example: When an infrared photon strikes an atom of carbon dioxide, energy is transferred into the molecule at the quantum level.
Note: This does not occur with nitrogen and such because of insufficient mass.
