Witryna16 wrz 2024 · A preference for gauche-type conformations is also observed in systems where two vicinal polar bonds are joined together at their more negative ends. One of the best-studied systems is hydrogen peroxide, where the preferred (gas phase) conformation is characterized by a H/O/O/H dihedral angle of 112°.

WitrynaTwo groups are found to be in gauche form when the dihedral angle between them is 6 0 ∘ 60^\circ 6 0 ∘ and in an anti-conformation when the dihedral angle is 18 0 ∘ 180^\circ 1 8 0 ∘. Similarly, for fully eclipsed, the two groups should be at 0 ∘ 0^\circ 0 ∘ dihedral angle, and for partly eclipsed it should be 12 0 ∘ 120^\circ 1 2 ...
