Abstract

Two independent novel theories are tested against each other by the determination of cross-sectional areas of a series of alkanoic acids: a recently developed method for the elucidation of molecular shape parameters; and fractal theory of adsorption. The numerical results obtained by the two approaches are virtually identical. It is concluded that the adsorption conformation of these acids on silica is horizontal. The two new approaches, which corroborate each other in this study, are described in detail, and a critical comparison to other methods for determination of molecular cross-sectional areas is made.
