title: Microwave enhanced polarization in a carbon dioxide molecule.
abstract: This paper presents the results of the dielectric response of carbon dioxide measured using a loaded microwave cavity operating in the TE011, mode of a cylindrical cavity near the frequencies 8.8, 9.7 and 10.2 GHz. The temperature dependence of the dielectric response of gas phase CO2 over the range of 160 to 213 degrees K (-113 to -60 degrees C) was measured. Slater perturbation equations for loaded resonant cavities were used to relate the macroscopic parameters deltaf and delta(1/Q) to the real and imaginary parts, epsilon' and epsilon", respectively, hence to calculate the dielectric parameters at each temperature and frequency. Selected peaks in the dielectric response were identified to indicate the frequencies at which strong coupling between the microwave field and the CO2 molecules can be achieved.
