Abstract: Employing the quasi-classical trajectory method and the potential energy surface of Panda and Sathyamurhy [Panda A N and Sathyamurthy N 2004 J. Chem. Phys. 121 9343], the effect of the reagent vibration on vector correlation of the ion-molecule reactions D- + H2 and H- + D2 is studied at a collision energy of 35.7 kcal/mol. Four generalized polarization-dependent differential cross sections (2$\pi$/σ)(dσ00/dωt),(2$\pi$/σ)(dσ20/dωt),(2$\pi$/σ)(dσ22/dωt), and (2$\pi$/σ)(dσ20/dωt) are presented in the centre-of-mass reference frame, separately. At the same time, the effects on the product angular distributions P(θr), P($\phi$r) and P(θr,$\phi$r) of the title reactions are also analysed. The calculated results show that the scattering tendencies of the product HD, the alignment and the orientation of j' sensitively depend on reagent molecule vibration.

Key words: quasi-classical trajectory, generalized polarization dependent differential cross sections, stereodynamics, vector correlation
