Abstract
In a recent work [J. Chem. Phys.122, 094906 (2005)], Porter and Lipson present a Born-Green-Yvon integral equation approach for computing the intramolecular distribution functions of a flexible interaction-site chain in a monomeric solvent. Although this Born-Green-Yvon construction appears to work for a hard-sphere chain-in-solvent system, here we show that the approach yields quantitatively incorrect results for the square-well chain-in-solvent system.
