Three distinct water structures at a zwitterionic lipid/water interface revealed by heterodyne-detected vibrational sum frequency generation
Lipid/water interfaces and associated interfacial water are vital for various biochemical
reactions, but the molecular-level understanding of their property is very limited. We
investigated the water structure at a zwitterionic lipid, phosphatidylcholine, monolayer/water
interface using heterodyne-detected vibrational sum frequency generation spectroscopy.
Isotopically diluted water was utilized in the experiments to minimize the effect of
intra/intermolecular couplings. It was found that the OH stretch band in the Imχ (2) spectrum …
