Quantum chemical methods can be benchmarked by investigating cold and isolated molecular clusters in supersonic expansions via FTIR spectroscopy. The long absorption path necessary for sufficient intensity leads to a high substance consumption. To tackle this issue, a new jet FTIR setup is introduced, reducing substance consumption by up to two orders of magnitude.
