Vibrational spectroscopy is an especially suited tool to investigate bonding configurations of chemisorbed species on solid surfaces. Here we employ high resolution electron energy loss spectroscopy to study the bonding structure of hydrogen, water and oxygen on Si(100) and Si(111) surfaces. Atomic ...
HYDROGEN BONDING IN THE ADSORPTION OF LIQUID AROMATICS ON OXYGEN-CONTAININ G ACTIVATED CARBON 来自 掌桥科研 喜欢 0 阅读量: 31 作者:HA Arafat,NG Pinto 摘要: Activated carbon has been used for a long time as an effective adsorbent for a wide variety of compounds. However, the specific ...
We previously provided experimental evidence that an extensive network of hydrogen bonds exists near the oxygen-evolving Mn4CaO5 cluster in photosystem II and that elements of this network form part of a dominant proton-egress pathway leading from the Mn4CaO5 cluster to the thylakoid lumen. The ...

This proposed mechanism is supported by in situ surface-enhanced Fourier-transform infrared spectroscopy and our simulation of PCET kinetics based on computed proton vibrational wavefunctions at the hydrogen-bonding interface. These findings highlight opportunities for using non-covalent interactions between...
Probing the Hydrogen-Bonding Network at Soft Matter and Metal:Metal:Oxide:Water Interfaces the Pt-CeO2 interface was extended to other metal-oxide interfaces(metal:Pt and Ni; oxide:CeO2,TiO2,ZrO2 and Fe3O4),all exhibiting excellent ... N Dalchand 被引量: 0发表: 2021年 Catalysis at Metal...
Iron(IV)oxo intermediates are involved in oxidations catalyzed by heme and nonheme iron enzymes, including the cytochromes P450. At the distal site of the heme in P450 CompoundI (FeIVoxo bound to porphyrin radical), the oxo group is involved in several hydrogen-bonding interactions with the pr...

For this to be so, the molecule must have a high electrical charge and it must be polarised. If the polarisation state of the molecule is changed then the absorption and emission ofinfraredradiation also changes. If the change in the hydrogen bonding percentage is less than twenty per cent ...
Force constants are not always found to vary monotonically with bond length, and the distinction between symmetrized and unsymmetrized force constants is emphasized in this connection. 展开 关键词: Hydrogen bonding Ab initio calculations Basis sets Excited states Hydrogen reactions ...
