Lay Summary (English)

Lead
Lay summary
The principal aim of the project is to spectroscopically characterizechemically and astrophysically interesting radicals and ions containingdominantly carbon. A number of techniques is used to measure theelectronic spectra in the gas phase. These then provide the means ofidentifying the species in terrestrial and space environments, and thedetails of the spectral features enable information of the conditions insuch hostile regions to be inferred as well as the fundamental knowledgeon their electronic structure. The species of primary focus are carbonchains, rings, fullerenes, their simple derivatives including a fewhydrogens, nitrogen or such, and ions. The reactive species are preparedin the gas phase in situ by means of plasmas produced in supersonic freejets, often from simple precursors as acetylene. Sensitive laser methodsare used to detect the electronic transitions. Studies of the spectra oflarger ions, held in a radiofrequency trap and collisionally cooled, arein development. Measurement of the spectra in neon matrices withmass-selected beams often provides the basis of the gas phase studies.
