in my book it says some covalent bonds absorb infrared radiation. it causes them to vibrate and absorb energy.

is the infrared radiation the energy which is absorbed or does it transmit energy and if so from what source? thanks

The start of this article should be able to explain what's happening in an easy to understand way.

Sorry, it worked a minute ago - don't know hat happened there!. Basically, covalent bonds jiggle about even at room temperature. They can stretch and swing about (bending) but only certain types of movements are "allowed". When infrared light is absorbed the bond can change from one type of movement to another. Try this link instead
