The contribution of the transition metal 3d electrons into formation of the ionic-covalent bonds In these ternary compounds, estimated from the XANES analysis and chemical shift of the absorption Edges, was found decreasing with the 3d shell occupation. 展开 年份: 1998 ...
The adiabatic bond dissociation energies for the P[Single Bond]N, P[Single Bond]O, and N[Single Bond]O bonds in NPO and PNO are the same within approximately 10 kcal/mol and fall in the range of 72-83 kcal/mol. 展开 关键词: CORRELATED MOLECULAR CALCULATIONS GAUSSIAN-BASIS SETS DIATOMIC...
At pH 9.0 the destruction of the helix produces an acidic sequence. The relative pH position of the helix transition, the fact that addition of salt increases the apparent helical content of BPA, and the observed acidic-type of sequence rule out the possibility of (1)ionic bonds between ...
Our results reveal that O-Ni ionic bonds are formed by Ni electron donation, while the Zr-Ni bonds show a mixed character with ionic and electron hybridization contributions.DOI: 10.1103/PhysRevB.68.075401 被引量: 9 年份: 2003 收藏 引用 批量引用 报错 分享 ...
Although MSA initial hydration and ionic dissociation have been studied by DFT, IR and Raman spectroscopy of these processes, as well as the behavior of MSA in aqueous solution are not completely resolved. In particular, the dynamics of MSA interaction with water molecules need further investigation...
Similarly, formation of triple-stranded DNA is hindered when the sequence is organized as nucleosomes. Efficient formation of triplex DNA occurs only at relatively high ionic strength (0.6 M NaCl), when the nucleosome is partially destabilized, and results in the disruption of the nucleosomal ...
It can be viewed as a solid ionic liquid30 featuring the Brønsted acid-zwitterion structure, but not a simple host-guest composite like those ILs@MOFs28. For the DSC plot within 0 ~ 320 °C, the first feature of the endothermal melting (offset ~127 °C) is broad and weak...
The molecules were oriented in the field so that one C−H bond was aligned with the field in the direction appropriate for a stabilizing polarization of that bond. Although the C−H bonds of acetylene and HCN lengthen as the field increases, that of methane shortens until the field ...
10), the structural region of CalA3 substantially contacts the catalytic region (Fig. 2a, b), resulting in interfaces that account for nearly 50% of the total buried surface area, with approximately 1421 Å2 on each side, mainly through hydrogen bonding and ionic interactions between the ...
