The study innovatively explores the ultrafast structural and vibrational dynamics of hydrated phospholipids, essential components of cell membranes. Utilizing advanced nonlinear vibrational spectroscopy techniques, particularly femtosecond two-dimensional infrared spectroscopy, the author reveals that interfacial water exhibits minimal fluctuations on a 300 fs timescale, while hydrogen bond lifetimes with phospholipids exceed 10 ps. These findings highlight the influence of steric hindrance and strong electric fields from phospholipid dipoles on water dynamics and energy dissipation processes.
