Figures , and 7 plot the local density of the solvent O around the ring S, (non-ring) sulfone S, and N of the solute. These interactions were chosen to capture the effect of hydrogen bonding; the solvent O was chosen as there is only one O per solvent molecule. It is common to consider the radial distribution function, g (r). Note that the local density and radial distribution function are related, with the radial distribution function equal to the local density normalized by the bulk density . Comparing neat and water-saturated 1-octanol, the solvent bulk density of O increases by approximately 20%, and the normalization of the radial distribution function can hide the local change, motivating the use of local density here. When considering the case of water-saturated 1-octanol, we do not differentiate between the solvent O from water and 1-octanol.
