The study presents recently measured experimental data for the surface tension of ordinary water at temperatures down to – 25 °C together with the results of the molecular simulations for the SPC/E and TIP4P/2005 force fields. The experimental data is close to the extrapolated IAPWS standard (2014) and to the correlation of Viisanen et al. (1993) commonly used in the nucleation studies. The presented experimental data and molecular simulations do not show any anomalous temperature course. An exponential growth predicted by Rogers et al. (2016) may occur at even lower temperatures.
