    • The phase observed to form at the surface from multicomponent solutions during the competitive adsorption experiments were not metastable, kinetically favored phases. This was determined by displacement experiments, where a monolayer was formed from pure solution and then rapidly displaced by addition of another isomer

    • Two polymorphs of 17-meta were discovered: form II was obtained from recrystallization from methyl ethyl ketone, and cooling from the melt of form II produced form I. The relative stabilities were determined by allowing saturated solutions of the two polymorphs of 17-meta in phenyloctane to equilibrate. These solutions were filtered, and the precipitates were compared by optical microscopy and powder X-ray diffraction, which indicated that both solids were form I. The same process was monitored in acetone using optical microscopy. The transformation of form II to form I indicates that form I is the more stable polymorph of 17-meta.
