Isotopic effects on the stereodynamics for the Ne+H2+/Ne+HD+/Ne+HT+ reactions

Graphical abstract: The isotopic effects on Ne+H2+/Ne+HD+/Ne+HT+ reactions are presented by stereodynamics calculations with quasi-classical trajectory method. Research highlights: → The isotopic effects on Ne+H2+/HD+/HT+ reactions are shown by stereodynamics. → The product rotational angular momentum vector are both aligned and oriented. → The isotopic effect on PDDCS is different to different products but same reactant. - Abstract: Isotopic effects on the stereodynamic properties of Ne+H2+/Ne+HD+/Ne+HT+ reactions are investigated using a quasi-classical trajectory method at a collision energy of 0.7 eV on a new surface constructed by Lv et al. (S.J. Lv, P.Y. Zhang, K.L. Han, G.Z. He, J. Chem. Phys. 132 (2010) 014303). The polarization-dependent generalized differential cross sections and alignments of the product rotational angular momentum for all reactions are reported. Remarkable isotopic effects in all reactions are observed. The relationship between the isotopic effect and the mass factor of the reactant atoms is also examined.
