The interaction between a water molecule and silver iodide clusters has been studied by means of the CNOO method. Two different adsorption forms obtained, one of which may initiate ice nucleation. The formation of a six-membered water molcculc ring above the surface requires less energy than its for

✦ Synopsis
We present ab initio molecular orbital calculations on vertical ionization potentials of surface and interior anion structures of I -( HzO), (n = 7, 8) clusters. The 'magic number' in the differential ionization potential of I-(HsO), is accounted for by the dominance of surface structures for n = 2-5, the 'transition' from a surface structure to an interior structure at n = 6 and the prevalence of the solvation shell closure for n = 7,8.
