TL;DR: The study has been extended, in a limited way, to the conformation of the ring in the amino acid proline, and it is found that any one of the five atoms can be out of plane (either way), with the other four lying nearly in a plane.

TL;DR: X-ray data compiled by Ramachandran and Ramakrishnan and available neutron diffraction data analysed in this paper are used for this purpose and different values of the parameters, A, b, B in the LS potential function can be obtained.

TL;DR: An interpolation method is described, using cubic expressions in R and in θ, by which a smooth transition is obtained from the hydrogen bond function Vhb, in the range in which it is valid, to the nonbonded function Vnb, valid for large R.
