On the Ag, Ni, and pt clusters, the benzene CH bonds are found to bend away from the surface by 2°, 8° and 19°, respectively, a result of carbon atom hybridization to maximize overlap with metal orbitals. For benzene chromium tricarbonyl, the CH bonds are calculated to bend 3° ...
The hybridization change of the carbon atoms from sp toward sp2 with acetylene chemisorption and from sp2 toward sp3 with ethylene chemisorption is also observed at 80 K. The Raman spectra provide evidence that benzene is chemisorbed predominantly in Π-bonded state to the Ni and Ag surface ...
These trends are also nicely confirmed by the NMR chemicalshifts of 31p and 13C1 nuclei ukiich show a clear deshielding, shown asAS and a large increase of the 1JPC1 coupling constants ikuich are in linewith a trend of the C1 carbon hybridization change from planar to pyramidal(ref. 9,...
The analysis of the stereochemistry begins by determining the hybridization of each atom: sp2 for each atom forming part of aromatic rings and amide bonds, sp3 for atoms forming part of the piperazine ring and s for all hydrogen atoms involved. Then, two different geometries can be identified:...

Layer-structured Ruddlesden–Popper (RP) perovskites (RPPs) with decent stability have captured the imagination of the photovoltaic research community and bring hope for boosting the development of perovskite solar cell (PSC) technology. However, two-dimensional (2D) or quasi-2D RP PSCs are encount...
1a. In contrast to the planar structure of pristine graphene, the carbon layer in fluorinated graphene, adopts an "armchair" configuration due to the sp3 hybridization of all carbon atoms. The two fluorine atom layers uniformly distribute across both basal faces. To explore the potential impact ...
Finally, Density Functional Theory (DFT) studies on 2, 3, and 3Zn revealed a planar structure with dsp2 hybridization and D4h symmetry in metallated porphyrins. Analysis of the HOMO-LUMO gap (ΔEH.L.) showed that zinc coordination in 3 increased the gap by 0.60 eV, mainly due to ...
The C atoms in the single bond need not be of the same hybridization. Carbon atoms form double bonds in compounds called alkenes and triple bonds in alkynes. An sp2-hybridized orbital and a p-orbital that is not involved in the hybridization form a double bond, while a triple bond evolves...
