Some experiments have witnessed increasing decoupling of viscosity from thetranslational self-diffusion of supercooled water with decreasing temperature.While theory and computer simulation studies indicated the jump translation ofthe molecules as a probable origin of the above decoupling, a precisequantitative estimation is still lacking. Through a molecular dynamics (MD)simulation study, along with careful consideration of translational jumpmotion, we have found the most definite proof of increasing relevance oftranslational jump diffusion in the above decoupling phenomena. By separatingout the jump-only diffusion contribution from the overall diffusion of thewater, we obtain the residual diffusion coefficient, which remains stronglycoupled with the viscosity of the medium at the whole temperature range,including supercooled regime. These new findings can help to elucidate manyexperimental studies featuring molecular transport properties, where strongdiffusion-viscosity decoupling comes into the picture.
