Phase space barriers and dividing surfaces in the absence of critical points of the potential energy: Application to roaming in ozone
Frédéric A. L. Mauguière, Peter Collins, Zeb C. Kramer +4
We examine the phase space structures that govern reaction dynamics in the absence of critical points on the potential energy surface. We show that in the vicinity of hyperbolic in…
Nonstatistical dynamics on the caldera
Peter Collins, Zeb C. Kramer, Barry K. Carpenter +2
We explore both classical and quantum dynamics of a model potential exhibiting a caldera: that is, a shallow potential well with two pairs of symmetry related index one saddles ass…
Roaming dynamics in Ketene isomerization
Frédéric A. L. Mauguière, Peter Collins, Gregory S. Ezra +2
A reduced two dimensional model is used to study Ketene isomerization reaction. In light of recent results by Ulusoy \textit{et al.} [J.\ Phys.\ Chem.\ A {\bf 117}, 7553 (2013)], t…
Roaming dynamics in ion-molecule reactions: phase space reaction pathways and geometrical interpretation
F. A. L. Mauguière, P. Collins, G. S. Ezra +2
A model Hamiltonian for the reaction CH CH + H, parametrized to exhibit either early or late inner transition states, is employed to investigate the dynamic…
Nonstatistical dynamics on potentials exhibiting reaction path bifurcations and valley-ridge inflection points
Peter Collins, Barry K. Carpenter, Gregory S. Ezra +1
We study reaction dynamics on a model potential energy surface exhibiting post-transition state bifurcation in the vicinity of a valley ridge inflection point. We compute fractiona…
Multiple Transition States and Roaming in Ion-Molecule Reactions: a Phase Space Perspective
Frederic A. L. Mauguiere, Peter Collins, Gregory S. Ezra +2
We provide a dynamical interpretation of the recently identified `roaming' mechanism for molecular dissociation reactions in terms of geometrical structures in phase space. These a…
