Abstract
The photothermal deflection technique applied to a gas thermal wave resonator seems to be one of the most powerful techniques to investigate in situ the thermal diffusivity of the gas. After a brief description of what a thermal wave resonator really is, a discussion is presented of the advantages and disadvantages of its use for measuring the gas thermal diffusivity.
