As we have learned after completion of this work, additional evidence indicating that strict anhydrous conditions seem to favor adsorption of true silane monolayers has been recently advanced: Untereker, D.

20. The Langmuir monolayers were spread at the water-air interface and transferred to the solid substrates as described in ref 2. According to molecular models C20 and OTS monolayers should have similar thickness.

25. Since the absorption measurements are performed such that the light beam scans a monolayer area of ca. 6-mm length2 and the slides are immersed and withdrawn at a speed of 2.7 mm/s, the real adsorption times are longer by ca. 2 s in the average.

27. It might be of interest to note that the curves in Figures 7 and 8 have the same functional form as the well-known Freundlich isotherm which is empirically applied to many adsorption systems.
