✦ Synopsis

In order to examine the solvating strength toward a cation species N: , the equilibria of clustering reactions N: (Ar)._, + 2Ar=N: (Ar),+Ar were studied with a pulsed electron beam high-pressure mass spectrometer. the thermochemical stabilities of N$ ( Ar ), with n > 2 were determined. The bond energies of N$ ( Ar ), show an irregular decrease with n = 2 + 3 and those with n> 3 become almost n independent. Through ab initio MO calculations, the above irregular decrease can be verified theoretically in terms of an anomalous switch of the charge center, N: +Ar+N*...Ar+.
