We demonstrate longwave infrared (6.6–11.4 μm) dual-comb molecular spectroscopy with some quarter million comb-line-resolved data points at up to a video rate. Acquiring such a massive amount of spectral information in real time was enabled by the use of a new class of femtosecond lasers combined with efficient frequency down conversion.
