Examples of bonds which absorb IR radiation are C=O, O-H and C-H bonds.
Greenhouse gases absorb infrared radiation and bounce it back out in all directions, including towards the Earth, keeping the Earth's atmosphere warm. This is known as the greenhouse effect.
Examples of greenhouse gases are carbon dioxide, water vapour and methane.
