Fragmentation of the (R)-(+)-1-phenyl-1-propanol radical cation ([(BZC 2H5)R]+) is markedly affected by asymmetric microsolvation (see picture). The CI±-C I² bond cleavage in the heterochiral [ (BZC2H 5)R.BDSS]+ cluster is more efficient than in th

The overall light intensity (fluorescence) of the sputtered atoms, ions, and molecules has been measured for polycrystalline AlN which was bombarded with 248 nm laser pulses in the presence of a background pressure of N 2 . AlN is unusual in that, in

The III group element nitrides (AlN, GaN, InN) have been prepared by laser ablation of the metals and simultaneous exposure to NH3. This study reports the growth of polycrystalline thin films of GaN on Si(100) by Nd:YAG (λ=532 nm) laser evaporation

One- and two-color, mass selected R2PI spectra of the S(1)-- S(0) transitions in the bare (R)-(+)-1-phenyl-1-propanol and its complexes with bidentate solvent molecules, like the (R)-(-)- and (S)-(+)-3-hydroxytetrahydrofuran enantiomers, have been re

Laser ablated chiral molecules and their clusters are studied by mass resolved R2PI technique. Attractive (electrostatic and polarization) and repulsive (steric) interaction influence both the shift and the binding energy of the complexes. In monofuc
