在化學中，扭轉角（英語：torsion angle）被定義為二面角的特定例子，描述了通過 ... New formulation for derivatives of torsion angles and improper torsion angles in ...

The torsion angle is considered positive if a clockwise rotation is required to bring atom Cl(1) into line with atom O(1). Clearly if ...

The torsion angle (dihedral angle) is defined by three consecutive bonds involving four atoms. The angle describes the rotation of the chain around the middle ...

A dihedral angle (sometimes called a torsion angle) is the angle between the two planes formed by the four groups (Figure 3.4). While the technical definition ...

The torsion angle can have any value from 0° to 180°. If the chain is viewed along the line BC, the torsion angle is positive if the bond AB would have to be ...

In this case the torsion angle is also called the dihedral angle. The angle ... The torsion angle φ as the angle between planes. φ = Tor (p1, p2, p3, p4) = τ ...

(a). Similarly, arrangements corresponding to torsion angles between 30° and 150° or between -30° and -150° are called clinal (c) and those between 0° and ...
