Dataset description
The diffusion of sugar in aqueous solution is important both in nature and in technological applications, yet measurements of diffusion coefficients at low water content are scarce. In our paper, “Sucrose diffusion in aqueous sucrose”, we report directly measured sucrose diffusion coefficients in aqueous solution. Using a Raman isotope tracer method, we monitor the diffusion of non-deuterated and deuterated sucrose across a boundary between the two aqueous solutions. As well as providing information of importance to the fundamental understanding of diffusion in binary solutions, these data have technological, pharmaceutical and medical implications, for example in cryopreservation. In the atmosphere, slow organic diffusion may have important implications for aerosol growth, chemistry and evaporation. This dataset contains all raw Raman spectra from which the diffusion coefficients presented in “Sucrose diffusion in aqueous sucrose” are calculated, as well as temperature and humidity data from the hygrometer measuring the conditions under which each experiment was performed.
