An artificial molecular motor has been studied by chirped‐pulse Fourier transform microwave spectroscopy. In their Communication on page 11209 ff., M. Schnell et al. combine high‐resolution spectroscopy with supersonic jets to capture a snapshot of the functional nanomachine in the gas phase. In the picture, a cold molecular beam of the molecular motors is probed using microwave fields with aligned dipole moments. The spectral film shows highly resolved rotational transitions, which led to an unambiguous structural assignment.
