Plasma-activated chemical transformations promise efficient syntheses of vital chemicals such as ammonia, however, reaction pathways are often unknown and quantum state-resolved information is lacking. Here, the authors use quantum cascade laser dual-comb spectroscopy to study non-thermal plasma-activated ammonia synthesis with rotational and vibrational state resolution, quantifying state-specific number densities via broadband spectral analysis.
