Probing the structures of gas-phase rhodium cluster cations by far-infrared spectroscopy

, : Probing the structures of gas-phase rhodium cluster cations by far-infrared spectroscopy. Journal of Chemical Physics 133(21): 214304-214304

The geometric structures of small cationic rhodium clusters Rh(n)(+) (n = 6-12) are investigated by comparison of experimental far-infrared multiple photon dissociation spectra with spectra calculated using density functional theory. The clusters are found to favor structures based on octahedral and tetrahedral motifs for most of the sizes considered, in contrast to previous theoretical predictions that rhodium clusters should favor cubic motifs. Our findings highlight the need for further development of theoretical and computational methods to treat these high-spin transition metal clusters.

Background: The prognosis for patients with scirrhous gastric cancer (SGC) is extremely poor. To improve the patients' prognosis, laparoscopic-assisted intraperitoneal chemotherapy (IPC) was introduced for SGC. In this study, we analyzed whet...

We demonstrate here a local- and remote-control of gel disintegration by using photoinduced proton transfer chemistry of photoacid generator (PAG). The gels were prepared by simply mixing two polymers, poly(N-isopropylacrylamide-co-5-methacrylamid...
