A Spectroscopical and Photochemical study on Covalent and Non-Covalent Bonds

The spectroscopical and photochemical properties of different aromatic molecules and aromatic clusters were studied using electronic spectroscopy. REMPI, Ion and Electron Imaging, ZEKE and MATI experiments were performed. Supersonic molecular beams were used to produce isolated phenols, phenol-water cluster, anisole dimer cluster and anisole-Ar(n) clusters. Thanks to high power laser sources, these systems were pumped above the dissociation threshold, ionic fragments were produced and their production was monitored. The binding energies in diferent quantic states were determined for the dissociation of clusters. Also a time-resolved Ion imaging experiment was performed on phenol and substituted phenols.
