In order to demonstrate the potential for CO2 gas to replace HCl gas in a common physical chemistry experiment, FTIR spectroscopy was performed on CO2. Techniques such as the inclusion of P2O5 in the gas cell were applied to reduce interference by water. This allowed for the resolution of bands resulting from rotational-vibrational coupling, which are necessary in determining molecular constants.
