Detailed Description

Calculate dihedral angles between particles in a polymer.

For \( n \) bonded particles, return the \( n-3 \) dihedral angles along the chain, in radians.

The sign of the dihedral angles follow the IUPAC nomenclature for the Newman projection, specifically section "Torsion Angle" pages 2220-2221 in [29].
