By measuring contact angles with water, glycerol and formamide on a number of polar surfaces, an estimate could be made of the electron-acceptor (γ+) and the electron-donor (γ−) parameters of glycerol (G) and formamide (F), relative to the parameters of. water (W), for which a reference value of γ+W= γ−W= 25.5 mJ/m2has been assumed. The values thus found are: γ+G≈ 3.92 mJ/m2(which yields γ−G≈ 57.4 mJ/m2) and γ+F≈2.28 mJ/m2(which yields γ−F≈ 39.6 mJ/m2).
