In this presentation, we report on the development of the Integration Log RDT method for independent determination of gas temperature from multi-component gas spectra acquired by dual comb spectroscopy. It is experimentally demonstrated that the method can be applied to molecular species that are difficult to be determined by conventional methods, and the method is also demonstrated to be applicable to a wider range of molecular species in HITRAN simulations.
