(a) The degree of hydrogen bonding as a function of the z coordinate, which is defined as the number of 1-butanol – 1-butanol, 1-butanol – water and water – water hydrogen bonds divided by the number of molecules in the first solvation shell.
(b) Orientational order parameter P profile for 1-butanol molecules as a function of its z location.
