Imaging of hydrogen halides photochemistry on argon and ice nanoparticles

Popis výsledku v původním jazyce

The photodissociation dynamics of HX (X = Cl, Br) molecules deposited on large ArN and (H2O)N, N 102?103, clusters is investigated at 193 nm using velocity map imaging of H and Cl photofragments. In addition, time-of-flight mass spectrometry after electron ionization complemented by pickup cross section measurements provide information about the composition and structure of the clusters. The hydrogen halides coagulate efficiently to generate smaller (HX)n clusters on ArN upon multiple pickup conditions.This implies a high mobility of HX molecules on argon. On the other hand, the molecules remain isolated on (H2O)N. The photodissociation on ArN leads to strong Hfragment caging manifested by the fragment intensity peaking sharply at zero kinetic energy.Some of the Cl-fragments from HCl photodissociation on ArN are also caged, while some of the fragments escape the cluster directly without losing their kinetic energy. The images of H-fragments from HX on (H2O)N also exhibit a strong cen
