Surface pressure−area isotherms (Π−A) of racemic and enantioenriched methyl 17,18-dihydroxyoctadecanoate (rac- and (17R)-17,18-DHO) at the air−water interface are very similar, while these esters show significant differences in infrared reflec

To obtain information about the influence of hydrogen bonding on the monolayer behavior and molecular packing, amphiphiles with two hydroxyl groups attached to different positions in the alkyl chain are investigated at the air-water interface using
