摘要: The review describes recent progress in the characterization of size-selected negatively charged clusters gas phase using vibrational predissociation spectroscopy. Examples from authors' laboratory are used to demonstrate way which spectra obtained and interpreted provide information on anion-neutral interactions. Infrared studies simple dimer complexes consisting hydrogen molecules attached halide anions (Cl m -H 2, Br I 2 ) described. From rotationally resolved 2.5 µm H-H stretch region one can deduce that have linear equilibrium structures ascertain intermolecular separations. Corresponding Cl -D isotopomers display a series clearly doublets, highlighting importance hindered internal rotation D subunit. Studies -(C H n, n containing up nine C illustrate how infrared ca...
