Correction to “Polarizable Model for DMSO and DMSO−Water Mixtures” Stephan J. Bachmann and Wilfred F. van Gunsteren* J. Phys. Chem. B 2014, 118 (34), 10175−10186. DOI: 10.1021/jp5035695 To our dismay, we have found an error in the calculation of the excess free energy ΔFexc for the polarizable DMSO/D model. This model is based on a damped, nonlinear molecular polarizability. In the calculation of ΔFexc, the damping parameter was erroneously not multiplied by a factor (4πε0)1/2 = 0.08483861 (kJ mol−1 e−2 nm)−1/2, which led to too much damping and the value ΔFexc = 28.9 kJ mol−1 in Table 2 and the solid lines in the upper panels of Figures 5 and 6. The correct value is ΔFexc = 31.4 kJ mol−1, and the correct curves for ΔFexc of mixtures of polarizable DMSO/D with polarizable COS/G2 water and with nonpolarizable DMSO molecules are given in Figures 1 and 2, respectively. All other results remain unchanged, and so are the conclusions. The authors would like to apologize for the inconvenience to the reader.
