Short summary

The viscosities of four polyols and three saccharides mixed with water were determined. The results from the polyol studies suggest viscosity increases by 1–2 orders of magnitude with the addition of an OH functional group to a carbon backbone. The results from the saccharide studies suggest that the viscosity of highly oxidized compounds is strongly dependent on molar mass and oligomerization of highly oxidized compounds in atmospheric SOM could lead to large increases in viscosity.
