A graphite fiber microbalance technique is used to study the growth mode of Kr, Xe, CH4, and CO films on graphite. The maximum thickness of the adsorbed film is finite below the triple points Tt of each of these adsorbates. The maximum thickness increases rapidly as T is brought toward Tt and levels off for TTt. This behavior is suggestive of a wetting transition that is pinned at the respective Tt of the adsorbates.
