Photoinduced Processes in Hydrogen Bonded System: Photodissociation of Imidazole Clusters

Original language description

The photodissociation of imidazole in hydrogen bonded clusters has been studied at photodissociation wavelengths 243 and 193 nm. Imidazole clusters of different mean cluster sizes n approximate to 3 and 6 have been produced in expansions with He and Ar carrier gases, and the mean cluster sizes were determined by mass spectrometric and crossed beam scattering experiments. Simultaneously, the (C3N2H4)(n) clusters were studied by ab initio calculations for n up to 4 molecules, confirming the hydrogen bondN-H center dot center dot center dot N motif in the clusters. The measured H-fragment kinetic energy distribution spectra exhibit a bimodal character similar to the KEDs found for the bare molecule.(1) At 243 run the fast H-atoms originate from the direct dissociation process on the repulsive pi sigma* state, and the slow component results from the dynamics Populating the vibrationally hot ground state via all S-1/S-0 conical intersection. In the clusters the contribution of the slow com
