Selective tunnelling effects in collinear chemical reactions

Tunnelling contributions to the reactive probability of both early- and late-barrier reactions are investigated. For the first class of reactions a new type of tunnelling effect taking place at high translational energy is discussed. For both reactions relations linking tunnelling features to the type of energy promoting reactivity are discussed with regard to the barrier location.

Specific chemical reactions reaction mechanisms 


Si esamina il contributo dell'effetto tunnel alla probabilità reattiva per reazioni con barriera anticipata e con barriera posticipata. Per la prima classe di reazioni si discute un nuovo tipo di effetto tunnel che ha luogo ad alte energie traslazionali. Per ambedue i tipi di reazione si discute il nesso esistente tra le caratteristiche dell'effetto tunnel e la forma di energia che è capace di favorire la reazione in relazione alla posizione della barriera.
