Laboratory 10 – Molecular Vibrations and the Greenhouse Effect Class: CHE 151 LB Name: Raven Gibson Partner(s): Jackson Sodrel and Connor Steeb Date: November 15, 2016 Introduction: The Earth absorbs solar energy and most of this energy is later released as heat, or IR radiation. The most abundant gas molecules in the atmosphere are O 2 and N 2 [2]. Carbon dioxide and methane, and other gases as well, absorb IR radiation from the Earth’s surface. These specified gases act like the glass in a greenhouse to increase the temperature of the planet, Earth. As for H 2 O, this is another significant greenhouse gas. Experimental method: For each listed molecule a program, Gaussian 09, is used to carry out a calculation of the geometry optimization and vibrational frequencies. These will be presented by a 3-D image of the molecule and a graph to show frequencies and intensities. Of the three gases tested which
