Abstract This paper presents the results of the dielectric response of carbon dioxide measured using a loaded microwave cavity operating in the 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 over the range of 160 to 213°K (-113 to -60°C) was measured. Slater perturbation equations for loaded resonant cavities were used to relate the macroscopic parameters Δf and Δ(1/Q) to the real and imaginary parts, ε’ and ε’’, 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 molecules can be achieved.
