torsionangle
The torsion angle, also known as a dihedral angle, is a fundamental concept in chemistry and molecular modeling used to describe the three-dimensional arrangement of atoms in a molecule. It quantifies the rotation around a central chemical bond. Imagine four atoms connected in a chain, A-B-C-D. The torsion angle is defined by the angle between the plane containing atoms A, B, and C and the plane containing atoms B, C, and D.
Specifically, the torsion angle is measured between the bond A-B and the bond C-D, with the axis
The conformation of a molecule, which refers to its spatial arrangement, is significantly influenced by its
