Abstract: [eng] [cze]
Influence of solvation on photodissociation of molecules is investigated in clusters produced in a molecular beam experiment. Photochemistry in three different systems is compared: (i) HBrArn and (HBr)n clusters, where the fragment does not react with the solvent and an effect of the fragment caging is observed, (ii) HBr(H2O)n system where chemical reaction occurs and a reaction channel is closed by the electronic interaction with the solvent. The practical relevance of the studied processes ranges from atmospheric chemistry to biology. Vliv solvatace na fotolýzu molekul je studován v klastrech v experimentech s molekulovými paprsky. Fotochemie tří různých systému je porovnávána: (i) HBrArn a (HBr)n klastry, kde fragmenty nereagují s klastrem a záchyt fragmentu je pozorován, (ii) HBr(H2O)n systém, kde dochází k chemickým reakcím a solvatací se otevírají nové reakční kanály, (iii) (Py)n klastry, kde dochází elektronickou interakcí se solventem k uzavření reakčního kanálu. Tyto studie mají praktickou relevanci v nejrůznějších oborech od chemie atmosféry po biologii.
