Abstract The ability to examine the vibrational spectra of liquids with nanometer spatial resolution will greatly expand potential study and liquid interfaces. In fact, fundamental properties water, including complexities in its phase diagram, electrochemistry, bonding due nanoscale confinement are current research topics. For any liquid, direct investigation ordered structures, interfacial double layers, adsorbed species at liquid–solid interfaces interest. Here, a novel way characterizing water high using transmission electron microscopy is reported. By encapsulating between two sheets boron nitride, capture quantify structure interaction liquid‐cell surfaces, identify isotopes H 2 O D energy‐loss spectroscopy demonstrated. microscope used here, equipped high‐energy‐resolution monochromator, able record molecules sensitive surface bulk morphological both nano‐ micrometer scales. These results represent an important milestone for isotope‐labeled materials characterization resolution, combining imaging spectroscopy.
