Numerical Integration of the Cartesian Equations of Motion of a System with Constraints: Molecular Dynamics of n-Alkanes

TL;DR: In this paper, a numerical algorithm integrating the 3N Cartesian equations of motion of a system of N points subject to holonomic constraints is formulated, and the relations of constraint remain perfectly fulfilled at each step of the trajectory despite the approximate character of numerical integration.

Molecular Dynamics Study of Liquid Water

TL;DR: In this paper, a sample of water, consisting of 216 rigid molecules at mass density 1 gm/cm3, has been simulated by computer using the molecular dynamics technique, subject to an effective pair potential that incorporates the principal structural effects of manybody interactions in real water.

Conformational Analysis of Macromolecules. II. The Rotational Isomeric States of the Normal Hydrocarbons

TL;DR: In this article, the conformational potential energy of the normal hydrocarbon molecules is considered to be a function of the dihedral angles of internal rotation about the carbon-carbon single bonds, the bond lengths and valence angles being held fixed.

Conformational analysis of n-butane

TL;DR: In this paper, the authors calculate the single point energy of butane in various conformations with respect to internal rotation around the C2-C3 bond and generate Excel charts of steric energy vs. dihedral angle.

Cubic Cell Model for Self‐Diffusion in Liquids

TL;DR: A cubic cell model for viscous flow and self-diffusion in liquids has been developed such that a linear Langevin equation for condensed systems can be deduced directly from the corresponding Navier-Stokes equation, the molecular friction coefficient being then related to the viscosity and cell size.
