Garett Tow’s paper on simulating the orthorhombic phase of ammonium perchlorate has been published (Garrett M. Tow and Edward J. Maginn, “Evaluating physical properties of the orthorhombic crystal phase of ammonium perchlorate using a class II force field”, Journal of Chemical Physics, 2018, 149, 244502.
In this paper, we show how a class II force field can adequately capture the structural, thermodynamic and spectroscopic properties of ammonium perchlorate.
