"Molecular theory for the phase equilibria and cluster distribution of associating fluids with small bond angles." <i>The Journal of Chemical Physics,</i> 139, (2013) AIP Publishing, LLC: 54902. http://dx.doi.org/10.1063/1.4816665.https://hdl.handle.net/1911/71732We develop a new theory for associating fluids with multiple association sites. The theory accounts for small bond angle effects such as steric hindrance, ring formation, and double bonding. The theory is validated against Monte Carlo simulations for the case of a fluid of patchy colloid particles with three patches and is found to be very accurate. Once validated, the theory is applied to study the phase diagram of a fluid composed of three patch colloids. It is found that bond angle has a significant effect on the phase diagram and the very existence of a liquidﾖvapor transition.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
