torsionsvinkler
Torsionsvinkler, also known as dihedral angles, describe the relative orientation of two planes or groups of atoms in a molecule. Specifically, it is the angle between the planes formed by two intersecting bonds. Imagine two planes that share a common edge; the torsionsvinkel is the angle you'd measure by rotating one plane around that common edge. In organic chemistry, this concept is fundamental to understanding molecular geometry and the stability of different conformations.
The torsionsvinkel is often denoted by the Greek letter phi (φ) or tau (τ). It's particularly important when
The range of possible torsionsvinkler is typically from 0 to 180 degrees, or 0 to -180 degrees,
