Hidden π ‐hydrogen bonded OH of water at negatively charged hydrophobic interfaces was revealed by two‐dimensional heterodyne‐detected vibrational sum‐frequency generation (HD‐VSFG) spectroscopy. In their Research Article on page 9498, T. Tahara and co‐workers show that the sign of the interfacial charge governs the structure and dynamics of water molecules facing the hydrophobic region. The picture illustrates 2D spectra tracking femtosecond hydrogen‐bond dynamics of water at charged hydrophobic interfaces.
