Cover Story: Conventional mechanical Fourier transform spectrometers (FTSs) measure absorption and dispersion spectra of gas-phase samples with very long measurement times to obtain time-resolved spectra with a good spectral resolution. Here, we present a mid-infrared dual-comb-based FTS providing broadband absorption and dispersion spectra with a spectral resolution of 5 GHz, a temporal resolution of 20 μs, and a wavelength coverage of 300 cm−1 in a measurement time of a few minutes. The spectrometer is used to monitor the reaction dynamics of methane and ethane in an electrical plasma discharge in dynamic conditions. The results demonstrate a new analytical approach for measuring rapid molecular changes in chemical reactions. This approach is interesting for chemical kinetic research, in particular for the combustion and plasma analysis community. View this paper
