Molecular Models of Greenhouse Gases

Oxygen, carbon dioxide, and methane are present naturally in the atmosphere. While carbon dioxide and methane are greenhouse gases, oxygen is not. Why not? To find the answer, go to the Cool Molecules Explore site.


On the top menu, click entry-level to reduce the total number of compounds. On the left pane, click bonds. On the periodic table, select molecules by clicking the individual atoms that form them (the molecules). For example, to select oxygen (O2) molecule, perform the following:


Click O, wait for a few seconds and then click O again.

Scroll below to see the list of molecules the O-O bond form. Locate the O2 (g) molecule and click view.

Below the molecular structure, a drop-down list contains the types of vibrations that the molecule and its bonds undergo. In the “show vibration” box, select each available vibration mode. Observe the way the atoms and bonds move for each mode.

Answer question 1 below.

Note: Sometimes when you select several vibration animations in a row (especially when you select the animations very fast), the simulation seems to lose track and stops. Just close the window and click view for the molecule again to continue.


Part A

Name oxygen’s only vibration mode and briefly describe its vibrational motion.


Part B

Close the simulation window for oxygen and return to the Cool Molecules Explore page.

Next, click C and then O in the periodic table. Find and view carbon dioxide (CO2) and view all the available vibrational modes of the molecule. In the table below, record the names of these vibrational modes and describe the vibration of the molecule in each mode.

Note: A molecule may have more than one way it can vibrate in each mode (a “state.”) These are shown in the simulation by multiple molecules vibrating side-by-side, so you can compare their motions. Record the number of unique possible states for each mode in the table.

Part C

Close the simulation window for oxygen and return to the Cool Molecules Explore page.


Next, click C and H in the periodic table and repeat the process for methane (CH4). In the table below, record the names of its vibrational modes and describe the vibration of the molecule in each mode. Also, record the number of unique possible states for each m

Part D

Based on your observations, compare the vibration of oxygen and the greenhouse gases, carbon dioxide and methane.

Part E

Based on the vibrational difference you observed, state a hypothesis to explain why diatomic molecules in the air, such as oxygen and nitrogen, are not greenhouse gases while those with 3 or more atoms, such as methane, are?
