In reality, it is teeming with special molecules: more than 300 different types have already been discovered. Many of these molecules, such as CCH⁺, are extremely unstable under Earth conditions. They can only exist thanks to the extreme vacuum and low temperatures in the ISM. To study these special molecules, we simulate these conditions in a laboratory setup at the FELIX Institute. There, we use free-electron lasers to characterise the molecules spectroscopically. Using complex quantum mechanical calculations, we interpret the results and make it possible to actually identify these molecules in space.","Radboud University, 03 juni 2025","Promotores : Redlich, B., Groenenboom, G.C.
