Photochemistry with fast sample renewal using cluster beams: formation of rare-gas halides in charge-transfer reactions in NF3-doped rare-gas clusters

Charge transfer reactions in free clusters are observed in a photoluminescence study on doped rare-gas clusters (Rg clusters, Rg=Ar, Kr and Xe). Following photoexcitation into the first absorption bands of Rg clusters, fluorescence from free RgF* excimers ejected from the clusters and from Rg2F* excimers localized in the interior of the clusters is observed. The results show that the reaction dynamics in clusters differs considerably from that in the gas and solid phase.
