Clockwise rotation gives dihedral angles from 0º to 180º.
180º is the same as counter-clockwise rotation to -180º.

#Unit 1. Molecules and their Interaction Relevant to Biology

Counter-clockwise rotation starting at 0º gives negative dihedral angles from -1º through

90º ending at -180º (the same dihedral angle  as +180º).
