摘要
Infrared photodissociation spectra of mass-selected Fe+-(CO2)(n) and Fe+-(CO2)(n)Ar clusters are reported. Under low power conditions, Fe+-(CO2)(n) clusters evaporate one CO2 molecule, while at higher fluence multiphoton absorption sorption leads to the loss of multiple ligands. Photo dissociation spectra show a blue-shift of the CO2 asymmetric stretch within the complexes which decreases with cluster size. Fe+-(CO2)(n)Ar clusters fragment by the loss of argon. Their spectra appear at the same frequencies as those for the corresponding pure Fe+-(CO2)(n) clusters, but with significantly narrower linewidths. The IR bands observed suggest specific structures for each of these complexes. (C) 2001 Elsevier Science B.V. All rights reserved.
