In molecular photodissociation, the thermionic emission, delayed emission and predissociation are the same? Otherwise, what is the difference between them?

My question is not about the solids, but I am saying about molecules/clusters.

Thermionic emission and delayed emission are normally properties of metals, or at least solids, and I can't see any relation to photodissociation of molecules. Can you make your question a bit clearer because it isn't obvious what you're asking. – John Rennie Mar 11 '13 at 18:14
@JohnRennie: Thermionic emission and delayed emission happens in clusters as well. My question is about the clusters. – albedo Mar 12 '13 at 12:43

Thermionic emission is the emission of electrons from a certain solid (usually metals, due to free electrons - good conductivity) which are in a thermally induced state of excitement. This excitement causes the electrons to emitted from said material.
