چکیده

The size-selective vibrational spectrum of Si4Xe in the 240-500 cm range has been recorded using infrared (IR) multiple photon dissociation spectroscopy. Comparison to linear IR absorption spectra of Si4 and Si4Xe calculated using density functional theory including dispersion corrections reveals an important influence of the Xe ligand on the structure of the cluster, involving significant charge transfer and formation of an incipient chemical Si-Xe bond with De=0.3 eV. • The IR spectrum of Si4Xe is obtained using infrared multiple photon dissociation • Its spectrum differs from that predicted for bare Si4, indicating a distinct influence of Xe • The interaction of Xe with Si4 results in the formation of an incipient chemical Si-Xe bond to be submitted for publication in Chem. Phys. Lett. on 04.02.2013

Nature of the interaction between rare gas atoms and transition metal doped silicon clusters: the role of shielding effects.

Mass spectrometry experiments show an exceptionally weak bonding between Si7Mn(+) and rare gas atoms as compared to other exohedrally transition metal (TM) doped silicon clusters and other SinMn(+) (n = 5-10) sizes. The Si7Mn(+) cluster does not form Ar complexes and the observed fraction of Xe complexes is low. The interaction of two cluster series, SinMn(+) (n = 6-10) and Si7TM(+) (TM = Cr, M...

Vibrational spectra and structures of bare and Xe-tagged cationic Si(n)O(m)⁺ clusters.

Vibrational spectra of Xe-tagged cationic silicon oxide clusters Si(n)O(m)(+) with n = 3-5 and m = n, n ± 1 in the gas phase are obtained by resonant infrared multiple photon dissociation (IRMPD) spectroscopy and density functional theory calculations. The Si(n)O(m)(+) clusters are produced in a laser vaporization ion source and Xe complexes are formed after thermalization to 100 K. The cluster...

Catalytic alcoholysis of tetramethylsilane via Pt-mediated C-H bond activation.

Tetramethylsilane reacts with 2,2,2-trifluoroethanol (TFE) in the presence of a cationic platinum(II) catalyst [(NN)PtMe(TFE)]+ (NN = 1,2-bis(3,5-dimethylphenylimino)butane). Catalytic Si-C bond heterolysis results in the formation of the trimethylsilyl ether, Me3SiOCH2CF3, accompanied by liberation of one equivalent of methane. Preliminary experiments suggest that a rate-determining C-H bond a...

Gas-phase structures of neutral silicon clusters.

Vibrational spectra of neutral silicon clusters Si(n), in the size range of n = 6-10 and for n = 15, have been measured in the gas phase by two fundamentally different IR spectroscopic methods. Silicon clusters composed of 8, 9, and 15 atoms have been studied by IR multiple photon dissociation spectroscopy of a cluster-xenon complex, while clusters containing 6, 7, 9, and 10 atoms have been stu...
