Short review on the acetylene photochemistry in clusters: photofragment caging and reactivity
Original language description
We have investigated solvent effects on acetylene photodissociation in clusters of different sizes and compositions generated in molecular beams: pure acetylene clusters (C2H2)(n), (n) over bar approximate to 10-200, and mixed (C2H2)(m) center dot Rg(n)(Rg = Ar, Xe) species where the single acetylene molecule or small cluster can be either adsorbed on the surface or embedded inside the rare gas cluster. We review our previous experiments in which the photodissociation dynamics was studied by the H-fragment time-of-flight (TOF) technique, and extend the experiments by measurements with a new velocity map imaging set up. We observe an unusual manifestation of the cage effect leading to a formation of fast hydrogen fragments. Such observation is interpreted as resulting from a two-step process: first, the initially excited molecule is quenched by the cluster cage to a vibrationally hot ground state; then the molecule dissociates upon subsequent photoabsorption from the vibrationally exci
