Novel detection of the C2v isomer of carbon tetraoxide (CO4)
نویسندگان
چکیده
Carbon oxides such as carbon dioxide (CO2) and carbon trioxide (CO3) have long been known as important molecules in atmospheric and solid state chemical reactions. Although higher order carbon oxides have been theoretically predicted to be stable and also important, their detection has been difficult. Here, we report on the first spectroscopic detection of the cyclic (C2v) isomer of carbon tetraoxide (CO4) via its m1 vibrational mode centered around 1941 cm 1 via low temperature infrared spectroscopy; the identification of the CO4, CO4, and CO4, isotopologues supported by ab initio calculations confirms the assignments. 2007 Published by Elsevier B.V.

Optical Excitation and Absorption Spectra of C 2 v and D 2 d Isomers of CO 4
Recently the CO4 isomer with C2v symmetry has been detected in an experiment [C. S. Jamieson et al., Chem. Phys. Lett. 440, 105 (2007)]. To further characterize this isomer, we report its optical excitation and absorption spectra calculated by the time-dependent density functional theory. Its rich spectral features are compared with those of another stable isomer having D2d symmetry. Their spec...

In this study, the novel surface ion-imprinted polymer (IIP) particles were prepared and applied as a electrode modifier in stripping voltammetric detection of lead(II) ion. A carbon paste electrode (CPE) modified with IIP nanoparticles and multi-walled carbon nanotubes (MWCNTs) was used for accumulation of toxic lead ions. Various factors that govern on electrochemical signals including carbon...
متن کاملFirst infrared spectroscopic detection of the monobridged diboranyl radical (B2H5, C2v) and its D5-isotopomer in low-temperature diborane ices.
With the use of a surface-scattering machine, layers of 27+/-4 nm diborane (B2H6) frosts were irradiated at 10 K and 10(-10) Torr with energetic electrons. The electrons induce a unimolecular decomposition of the diborane molecules and lead to boron-hydrogen bond rupture processes. Here, we report the first infrared spectroscopic detection of the monobridged diboranyl radical (B2H5, C2v) via th...
