Fig 2. Quantification of diffusion coefficient of EC-ethanol and pure ethanol with Raman spectroscopy.

Fig 2

(A) Representative ethanol concentration measurements for 6% EC-Ethanol measured with Raman spectroscopy and fit to a diffusion curve for Deff of 1.9x10-6 cm2/s. (B) Representative ethanol concentration for pure ethanol measured with Raman spectroscopy and fit to a diffusion curve for Deff of 5.4x10-6 cm2/s. (C) The effective diffusion coefficient was slower when using EC-ethanol (n = 7) compared to pure ethanol (n = 6). Bars indicate SD. *P<0.05 using Tukey’s HSD test.
