A novel non-active model to account for the leak of zero-point energy in trajectory calculations. Application to H+ O2 reaction near threshold

AJC Varandas - Chemical physics letters, 1994 - Elsevier
A novel non-active model to correct for the leak of zero-point energy in quasi-classical
trajectory calculations is proposed. It consists of eliminating every trajectory that fails to …

Energy switching approach to potential surfaces: An accurate single‐valued function for the water molecule

AJC Varandas - The Journal of chemical physics, 1996 - pubs.aip.org
A novel scheme is suggested to construct a global potential energy surface by switching
between representations which are optimal for different energy regimes. The idea is …

Mechanisms of H2 dissociative adsorption on the Pt (211) stepped surface

DA McCormack, RA Olsen, EJ Baerends - The Journal of chemical …, 2005 - pubs.aip.org
We utilize classical trajectory calculations to study the reaction dynamics of the dissociative
adsorption of H 2 on the stepped Pt (211) surface. The potential-energy surface has been …
