ROLE OF REAGENT VIBRATION IN H-2 CU DYNAMICS

Quasiclassical trajectory calculations of the dynamics of dissociative chemisorption of H-2 on Cu on different potential energy surfaces yie ld qualitatively the same result: vibrational excitation brings down t he translational threshold for dissociative chemisorption and there is very little vibrational excitation of H-2 with increase in relative t ranslation even when the dissociative channel is open. However, despit e these common features there are differences between the dynamical fe atures on the different surfaces.
