Abstract
In this article, we report an experimental method to calculate the values of the elastic constants that correspond to longitudinal and transverse vibrations in the classical model of the CO2 molecule. In classical molecular physics, the CO2 is treated as a linear array of three point-particles that interact by a harmonic coupling. The experimental wavenumbers of the normal modes of vibrations of CO2 were obtained from IR spectroscopy on an atmospheric air sample, and they were applied the calculation of the respective normal mode elastic constants. This article does not provide new research in molecular physics, but it is rather made for teaching purposes.
