Abstract
This document provides a basic format for computing the intensities of the rotational spectra absorption peaks for carbon dioxide. The documents introduces the use of a Laurentian function, and the contributions due to quantum mechanics namely, degeneracy, fraction of molecules in vibrational and rotational states, and the dipole moment to a calculation of the absorption intensities. Units are sued throughout the document. Students can use the document to study the significance of each contribution to the absorption intensity. They can also modify the document to study other polar diatomic gases such as HCl. The document can also serve as a classroom tool for discussions of the features of rotation absorption spectra.
