✦ Synopsis

Both a new direct interaction model {DIPR model) and the polarization theory of Wolfgang et al. are shown to be consistent wivith certain experiments for the reaction Ar+ + D2 = Ar+D + D despite their radically different assumptions about the dynamics of reaction. In the last few years, detailed experimental results [l-4] have become available for various ion-molecule reactions of the type A+-+BC=A+B+C. In particular, Wolfgang and his co-workers [5] have studied the reactions Ar+ + Dq = Ar+D + b and Are + Hq = Ar+H + H over the low to intermediate ene&y range 2 5 E 5.46 kcal/mole (all energies are in the centre-of-mass system and in units of kcal/mole unless otherwise stated), and have measured the translational exoergicity of the reaction, Q, over this energy range.
