The designation for the angle of rotation of the α-carbon–nitrogen bond is ϕ, whereas that of the α-carbon–carbonyl carbon bond is ψ. Although theoretically an infinite number of ϕ and ψ angles are possible around single bonds, only a limited number of ϕ and ψ angles are ...
What is the bond angle of the O−C−O angle of CO2? 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 ori...
While the smaller bond angle (defined as β) and the distance between the CrAs chains also affect the superconductivity due to their structural connections with the α angle. We find that the larger value of α-β, which is associated with the extent of the non-centrosymmetry of the lattice...

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 ...

number of two. The bond angle is linear, or 180 degrees, when the atom has no lone electron pairs. An example is carbon dioxide. Conversely, a nitrogen molecule has one lone electron pair. This gives it a linear shape but an unhybridized orbital and therefore it has no bond angle. ...
