It has been observed that one-bond 13C 13C coupling constants are almost invariant with C C bond angles between tetrahedral and 127° for hydrocarbons where the central atom is a CH 2 group. An empirical quadratic equation is obtained which relates 1J CC with the internuclear C C C angle...

We show a very significant opening of angle CZC and an important symmetrical distortion of C<SUB>3</SUB>C- groups by expansion (Z = NO, S, O) or compression (Z = C, NH, NMe, NS, P, Si). We discuss the effect upon the apparent size of tertiary groups....
2c). This rotation was mediated by residues Q33 and E34, with ψ dihedral angle-changes of −105.1° and −49.3°, respectively. The AT domain is composed of a large α/β-hydrolase-like subdomain and a ferredoxin-like small subdomain (Fig. 2f), similar to the known AT and MAT ...

Bond Angle: The bond angle can be explained as an angle between two adjacent atoms or electron pairs in certain molecules. This angle helps with the geometrical identification of a given molecule according to its atoms' specific orientations. ...
Catalyst deactivation caused by the aggregation of active metal species in the reaction process poses great challenges for practical applications of supported metal catalysts in solid-liquid catalysis. Herein, we develop a hypercrosslinked polymer integr
A hydrogen atom was deemed to be in hydrogen bonding position if the angle Cα-H···O ≥ 90°. Separate searches were conducted for the bifurcated hydrogen bond (both angles ≥ 90°), single Cα-H···O=C hydrogen bond (one angle ≥ 90°, the other < 90°) and no hydrogen ...
(Supplementary Fig.15). The ligand effect45caused by Ag doping in Cu also has the potential to affect C1–C1and C1–C2coupling. To evaluate the effect of the strain and ligand, we built a model with the same strain of Ag-doped Cu but without Ag substitution by fixing the bond length ...
(17%) due to restricted conformational freedom and bond angle compression. Herein, theZ-configuration of product3A′ implied the involvement of theanti-alkoxypalladation process in the cyclization41,42. Moreover, 4-phenyl-3-buten-1-ol converted well (3ua). Cyclic alcohol such as 2-cyclohexene-...
