RM vs. Ho relationships of two homologous series of pyridyl alkyl ketones were determined for systems of the type organic solvent/aqueous hydrochloric acid. In accordance with theoretical anticipations, linear 22~ vs. Ho plots were obtained for Ho values in the range -I, +I, RM values for methylene
