Abstract
The ion-molecule reactions (I) N?éé + N?éé + = N?éä + (II) Ar + N?éä + = N?éé+ ArN?éé + and (III) Ar + ArN?éé + = N?éé + Ar?éé + were studied with a pulsed time-of-flight mass spectrometer using an electrical discharge ion source. These reactions occurred mainly in a 1.05-cm drift tube, through which ions were drifted into the mass spectrometer at such low E/P that field-heating effects on ions were negligible. Equilibrium constants for Reaction (I) were determined at 673 and 738??K from 4 to 12 torr. Equilibrium constants were also determined for Reactions (II) and (III) at P (subscript Ar) /P (subscript N?éé) = 0.125 to 1.0 from 313 to 738?? K. Two vibrational models, the Degenerate and the Geometrical series models were used to process the data on a computer. The thermodynamic data for each of the reactions and bond energy data for N?éä+, ArN?éé+, and Ar?éé + were obtained. It is concluded that N?éä, ArN?éé+ and Ar?éé+ are stable ion clusters. Their appreciable bond energies are mainly due to charge exchange interactions in the clusters
