Not merely sloshing around: The chemical and physical properties of water are very important. In contrast to its simplistic chemical formula, water possesses a complex dynamic behaviour (see picture). The bend, torsion, symmetric and asymmetric stretch modes of liquid water, close to the wavelength of the laser line have been predicted. Here, the low‐frequency Raman spectrum of liquid water is presented confirming the presence of all four modes in the restricted translational region (35–300 cm −1 ).
