✦ Synopsis
We investigate the 'one-atom cage effect' in the ultraviolet photodissociation of HC1 in the Ar • • • HC1 van der Waals complex, in particular the possibility of resonance structures caused by trapping of the hydrogen atom between its heavy partners Ar and C1. The dynamics are treated by solving exactly the time-dependent Schr/Sdinger equation using the usual Jacobi coordinates for a triatomic molecule. The kinetic energy distribution of the H atom and the absorption spectrum are both completely structureless, demonstrating that trapping of hydrogen is negligibly small and ruling out the cage effect in Ar... HC1.
