The nature of the interoxygen bonding in O2, HO2, H2O2, O3, HO3, and H2O3has been investigated on the basis ofab initio(LCAO‐MO) and experimental force constants, bond lengths, and energies. The fact that small basis sets appear to give the OO force constants for H2O2and HO2in ...
Ag2+(O2)n clusterEquilibrium methods were used to measure binding energies and entropies for the attachment of up to four O2 ligands to ground-state Ag+(1S, 4d10) and for the attachment of up to three O2 ligands to ground-state Ag2+(2Σg, 4d20 σ(5s)1). Bond dissociation energies...
However, only a single vibrational transition in (H2S)2is predicted to be intensive enough for observation in this frequency range. Thus, the assignment of the IR spectra was up to now a puzzle to be solved. Here, we present an intermolecular potential surface and use it to predict the dif...
Bonding in the ground state of C2 is still a matter of controversy, as reasonable arguments may be made for a dicarbon bond order of 2, 3, or 4. Here we report on photoelectron spectra of the C2− anion, measured at a range of wavelengths using a high-resolution photoelectron imaging...
The oxidation rate is stimulated 10-fold by O2 and the products become acetone and NO-2... DJT Porter,HJ Bright - 《Journal of Biological Chemistry》 被引量: 135发表: 1983年 Preparation of tripyrrane analogues from resorcinol and 2-methylresorcinol for applications in the synthesis of new ...

Nuclear-resonance techniques are used to determine the magnetic and electric quadrupole interactions of the nuclei of all ions (except O2-) in the two compounds. From the thus derived spatial unpaired-spin density in the crystals informa... T.O. Klaassen and A. Gevers and N.J. Poulis - 《...
Se4 and Te4 clusters, the intermolecular weakly bound charge-transfer complexes (Se2)(O2) and (Te2)(O2), and the (X2)(Y2) and (XY)(YX) mixed compounds (X, Y = S, Se, Te) were studied using density functional theory with all-electron and effective core potential basis sets. All...
