"Resummed thermodynamic perturbation theory for bond cooperativity in associating fluids with small bond angles: Effects of steric hindrance and ring formation." <i>The Journal of Chemical Physics,</i> 140, no. 16 (2014) AIP Publishing: http://dx.doi.org/10.1063/1.4871307.https://hdl.handle.net/1911/94377In this paper we develop a thermodynamicﾠperturbation theoryﾠfor two site associating fluids which exhibitﾠbondﾠcooperativity (system energy is non-pairwise additive). We include both steric hindrance andﾠringﾠformationﾠsuch that theﾠequation of stateﾠisﾠbondﾠangle dependent. Here, theﾠbondﾠangle is the angle separating the centers of the two association sites. As a test, newﾠMonte Carlo simulationsﾠare performed, and theﾠtheoryﾠis found to accurately predict the internal energy as well as the distribution of associated clusters as a function ofﾠbondﾠangle.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
