Description

This animation illustrates the absorption of infrared radiation by CO2 in the troposphere and the collisional loss of this absorbed energy to surrounding N2 and O2 molecules. In this animation the user can sweep through a region of the IR spectrum and excite some of the vibrational modes of CO2. A simple (purely qualitative) thermometer illustrates the rise in temperature of the gas as collisional de-excitation occurs.
