Photodissociation spectra of naphthalene cluster ions (C[sub 10]H[sub 8])[sub n][sup +], n = 2 [minus] 7: Evidence for dimer core structure and comparison with neutral clusters
- Univ. of Akron, OH (United States)
The photoabsorption spectra of naphthalene cluster ions, (C[sub 10]H[sub 8])[sub n][sup +] with n = 2 [minus] 7, in the visible and near-IR (500-1100 nm) spectral regions have been observed by mass-selected photodissociation spectroscopy. These cluster spectra show two distinct absorption maxima centered at 1 [mu]m and 570 nm and match well the absorption spectra of the dimer ion previously obtained in solutions. The near-IR band is assigned to the characteristic intervalence transition of the dimer ion produced in these cluster, while the visible and band is attributed to a local excitation corresponding to the monomer D[sub 2] [yields] D[sub 0] transition. Both absorption bands are found to be independent of cluster size, which is explained by assuming a core structure involving a strongly bound dimer ion. The stability and dissociation dynamics of the ionic clusters are compared with those of the corresponding neutral clusters. 34 refs., 7 figs.
