Mo ð W Þ n O m ( n = 1 – 33 ; m = 2 – 75 ) clusters in the gas phase
نویسندگان
چکیده
H2MoO4 and H2WO4 upon direct laser desorption produce small clusters in the gas phase, extending up to 4500 and 7200 Da, respectively. The clustering patterns are quite similar for the two systems. The mass difference between successive peaks differ with increasing mass number as different kinds of structures become possible. A distinct planar to three-dimensional structural cross over is observed around the M8 cluster. Possible structures of these clusters are presented. MoO3 and WO3 were also used as starting materials, which yielded the same clusters. 2004 Elsevier B.V. All rights reserved.

The first systematic study of the CrðH2OÞ n ðnZ1K4Þ series of clusters is herein presented at the level of the unrestricted DFT B3LYP level in conjunction with electron core potential basis sets. The present structures are relevant for laser-induced and laser-ablation syntheses of chromium compounds, and also for fundamental spectroscopy studies of metal-bearing species in the gas phase.
