Intermolecular hydrogen bond in Supramolecular liquid crystal from mesogenic pentyloxy benzoic acid with non-mesogenic toulamide moities that arise due to non-covalent interaction has been studied. Polarizing optical microscopic investigations revealed monotropic crystal G phase while enantiotropic nematic phase in the prepared compound and pure liquid crystal. The liquid crystalline phase transitions were confirmed differential scanning calorimeter. Intermolecular Hydrogen bonding and the structural determination in the liquid crystalline amide were performed by the FTIR spectroscopy. The detailed study of FTIR in 5OBA, TMD and 5OBA:TMD samples were carried out and revealed strong intermolecular hydrogen bond between the pentyloxy benzoic acid and Toulamide..
