The Extreme Low-Frequency Raman Spectrum of Liquid Water Dr. Michelle Galvin, Dr. Dominic Zerulla UCD Dublin, School of Physics, Dublin 4 (Ireland), Tel: (+353) 1 716 2057, Fax: (+353) 1 283 7275 Email: Dr. Dominic Zerulla (dominic.zerulla@ucd.ie) Article first published online: 25 FEB 2011 DOI: 10.1002/cphc.201000894 Not merely sloshing around: The chemical and physical properties of water are very im- portant. 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 ).
