Abstract
The laser-induced fluorescence spectra of ionic clusters $C_{6}F_{6}^{+}=X_{N}$ are obtained by two-photon ionization of $C_{6}F_{6}$ seeded in a supersonic jet expansion of a mixture of Ne , Ar , or $N_{2}$ with He, or pure He. In the case of X-He and Ne, simple progressions in the cluster modes are observed. Quantitative understanding of the $C_{6}F_{6}^{+}-$He spectrum is possible using a model of the ion-inert gas potential. For $C_{6}F_{6}^{+}-Ar_{N}$ at relatively low Ar concentration, i.e. - 1.0\%, a progression of sharp peaks has been observed in contrast to the broader transitions observed at higher Ar concentrations. The red shifts of the cluster origin is about $400 cm^{-1}$. The spectrum of $C_{6}F_{6}^{+}-(N_{2})N$ shows a similar structure, but with a smaller red shift. The detailed spectral information will be given.
