R. Vonpietrowski et al., PHOTOCHEMICAL PROCESSES IN DOPED RARE-GAS CLUSTERS STUDIED WITH LUMINESCENCE SPECTROSCOPIC METHODS, Faraday discussions, (108), 1997, pp. 175-185
Photochemical processes in Xe and NF3 doped rare gas clusters Rg(N) (R
g = Ar, Kr, Xe) are investigated with luminescence spectroscopy using
photo-excitation with synchrotron radiation. Relaxation processes in X
e doped Ar-N clusters depend considerably on the location of the Xe at
om in the cluster. Following excitation of surface sites desorption of
electronically excited Xe atoms in the P-3(1) state is a dominant dec
ay channel. Xe atoms in the interior of the cluster emit inside bubble
s. The results are discussed in view of recent molecular dynamics (MD)
simulations. Electronically excited Rg(N) clusters doped with NF3 emi
t luminescence bands attributed to RgF and Rg(2)F*. This result gives
strong evidence for the first charge transfer reactions in clusters.
