Using Newman projections, rotating around a specific bond to reach other conformers is a fairly straightforward task. The best way to reach other conformers is to rotate just one carbon at a time, either the front carbon or the back carbon. For consistency it will always hold the front of the Newmann projection fixed and rotate the back carbon. May 01, 1999 · A method of illustrating the Newman projection of a molecule using an overhead projector is described. This method, which uses two overhead transparencies linked by a thumbtack, provides both an easy and a clear way to present this type of conformational analysis to large lecture classes.

Peptide Torsion Angles. The figure below shows the three main chain torsion angles of a polypeptide. These are phi, psi and omega. The planarity of the peptide bond restricts omega to 180 degrees in very nearly all of the main chain peptide bonds.

This interaction can be seen in a Newman projection of the bond between the carbons bearing the methyl groups: This gauche-butane interaction contributes 2.8 kJ mol_ 1(0.7 kcal mol_) to the energy of confor-mation B (Fig. 2.5, p. 54). The relative energy of the two conformations is the difference between Molecular mechanics uses a force field to calculate the steric energy of the molecule and then adjusts the conformation of the molecule to minimize the steric energy. A force field is set of parameters for the bond lengths, angles, torsional parameters, electrostatic properties, van der Waals interactions, etc.
