Helical structure formation and its breaking.

Abstract

<p>H-3 to H basin shifts indicate formation of helix as a result of left handed rotation of the χ₁ rotor and right handed rotation of ϕ by 80° while helix breaking the rotors assume reverse orientations. The ψ rotor maintains its right handed rotation throughout helix formation and breaking.
