An angle dependent site-renormalized theory for the conformations of n-butane in a simple fluid
The angular dependent site-renormalized integral equation theory is developed to compute the dihedral conformation distribution and intermolecular pair distributions of n-butane at infinite dilution in a Lennard-Jones solvent. The equations take advantage of the topological diagrammatic expansion...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The angular dependent site-renormalized integral equation theory is developed to compute the dihedral conformation
distribution and intermolecular pair distributions of n-butane at infinite dilution in a Lennard-Jones
solvent. The equations take advantage of the topological diagrammatic expansion of the full angular dependent
molecular system by resumming the series in conjunction with the intramolecular degree of freedom. To
first order in an angular basis set, the numerical results of these site-renormalized equations are a systematic
quantitative improvement over previous methods. In particular, the thermodynamics and conformational
distribution of the solute are essentially indistinguishable from simulation. |
