24. We found only one paper (Sondag-Huethorst, J. A.; Fokkink, L. G. J. Langmuir 1992, 8, 2560), in which the wetting property of Authiol SAMs was characterized by the Wilhelmy technique. But, they used polycrystalline gold electrodes (bulk gold mechanically cut and polished) whose surfaces were not adequate for the study on intrinsic wettability of SAMs.

33. Errors arose from estimation of the plate perimeter and also from different surface conditions at the section.

35. Tilt angle φ and systematic error due to the asymmetric force were estimated as shown in parts b and c of Figure 2. In the estimation, a set of sample and sample clip was assumed to be one rigid body weighing 1.4 g and hanging by a stirrup from the electrobalance. The tilt angle φ depressed with an increase in the weight. The estimated error is larger than the tilt angle φ and the difference between them is depressed with an increase in the weight. Under our experimental conditions, the error was slightly (<0.08°) larger than the tilt angle φ (Figure 3).
