Video Micro-lecture: Modes of Vibration in Greenhouse Gas Molecules
A micro-lecture that describes the vibrational modes of polyatomic molecules, how these modes determine whether the molecules are IR inactive or IR active and explains why most IR active polyatomic gas molecules are greenhouse gases.
