ff14SB: Improving the Accuracy of Protein Side Chain and Backbone Parameters from ff99SB

TL;DR: Together, these backbone and side chain modifications (hereafter called ff14SB) not only better reproduced their benchmarks, but also improved secondary structure content in small peptides and reproduction of NMR χ1 scalar coupling measurements for proteins in solution.

The relationship between proton-proton NMR coupling constants and substituent electronegativities—I : An empirical generalization of the karplus equation

TL;DR: In this paper, a new coupling constant-torsion angle relation for the three-bond 1H-1H spin-spin coupling constant is formulated, which includes a correction for the electronegativity of substituents.
