IR Spectroscopic Characterization of Methane Adsorption on Copper Clusters Cu ( = 2-4).

The interaction of CH with cationic copper clusters has been studied with infrared-multiple photon dissociation (IRMPD) spectroscopy. Cu ( = 2-4) formed by laser ablation were reacted with CH. The formed complexes were irradiated with the IR light of the free-electron laser for intracavity experiments (FELICE), and the fragments were mass-analyzed with a reflectron time-of-flight mass spectrometer.

IR Spectroscopic Characterization of H Adsorption on Cationic Cu ( = 4-7) Clusters.

IR spectra of cationic copper clusters Cu ( = 4-7) complexed with hydrogen molecules are recorded via IR multiple-photon dissociation (IRMPD) spectroscopy. To this end, the copper clusters are generated via laser ablation and reacted with H and D in a flow-tube-type reaction channel. The complexes formed are irradiated using IR light provided by the free-electron laser for intracavity experiments (FELICE).
