A quasi-classical trajectory study of the H + H/sub 2/ and D + H/sub 2/ reactions has been carried out at E/sub rel/ = 0.65 eV. The calculations were carried out for both the Porter-Karplus and Siegbahn-Liu-Truhlar-Horowitz potential energy surfaces. Very accurate determinations have been made of the product vibrational, rotational, and translational energy distributions using Fourier analysis. The results for the different reactions and different surfaces are compared with each other and with other work on these systems. The results indicate that there is little coupling between vibrational and translational degrees of freedom except very near the transition state. 7 figures, 4 tables.
