  explanation. Attempts at depositing chiral L.B. multilayers of (+)-C18H37SO-p-tolyl were not successful because of crystallite formation on the quartz support. Multilayers of (+)-S-octadecyl cysteine were deposited successfully, albeit with a monolayer of stearic acid interposed every seven monolayers of the chiral compound. No optical rotation was observed in the films.
