✦ Synopsis

By means of a density functronal trea1ment and a slab model for the density profile of the fluid, evphnt corrections to rhe classlal macroscopic formulae for the pressure at which captiry condensation occurs and for captirg rise are derived. Ille corections mvolve a multiple of the thrckness of the wetting film whose value is related directly to the exponent characterizlng :he e!gebrax decay of the attractive wall-fluid potential For a given undernturatlon, wettmg films are ttncker in clpdlarres than at nngle walls Volume 114, number 4 CHEMICAL PHYSICS UTTERS
