Webb16 sep. 2024 · The molecular orbital with the highest energy has two nodes that bisect the O–O σ bonds; it is a π * antibonding orbital. The third molecular orbital contains a single node that is perpendicular to the O 3 plane and passes through the central O atom; it is a nonbonding molecular orbital. WebbThe repeating structure of the backbone of a polypeptide is shown below, as it is usually drawn. The bond torsion angles, describing rotation about these bonds, are labeled (psi (and omega (w). In reality, significant rotation can occur about just two of these bonds. This problem has been solved!
