RESONANT 2-PHOTON IONIZATION PROCESSES OF VAN-DER-WAALS ADDUCTS - SPECTROSCOPY AND REACTIVITY OF STYRENES CLUSTERED WITH VARIOUS MOLECULES

Research on the formation and properties of clusters of aromatic molecules bonded to numerous solvents is rapidly expanding. Recently much attention has been paid to these adduct species with the objective of clarifying nucleation phenomena. Photophysical and photochemical studies of these clusters give information on solvent effects, intracluster reactions and charge-transfer processes. Model calculations of potential surfaces of vdW adducts have provided knowledge of the intracluster binding energy and vdW vibrational modes in a few systems. Here, data are reported on resonant two-photon ionization R2PI mass spectra and on spectroscopic shifts of styrenes clustered with various atoms and molecules.
