A reading that discusses how chemical bonds in molecules respond to incident IR light and absorb IR energy during certain modes of vibration. The reading includes discussions on the vibrational modes of water vapor and carbon dioxide (CO2) molecules and explains why these gases act as greenhouse gases.
Students will learn how the absorption of incident IR radiation by water vapor and carbon dioxide gas molecules in certain vibrational modes makes them behave as greenhouse gases.
