One-of-a-kind spectrometer reads vibrations between atoms to find structures of molecules A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards. By measuring the vibrations between atoms using femtosecond-long laser pulses, the Rice lab of chemist Junrong Zheng is able to discern the positions of atoms within molecules without the restrictions imposed by X-ray diffraction (XRD) and...

Brett Smith for redOrbit.com - Your Universe Online Using computer modeling, researchers at the University of California, San Diego and Emory University have revealed new details surrounding hexamer structures that are considered to be the smallest droplets of water. "Ours are the first simulations that use an accurate, full-dimensional representation of the molecular interactions and exact inclusion of nuclear quantum effects through state-of-the-art computational approaches,”...

Determining the molecular configuration of proteins is important in nanotechology, drug design, disease research and many other fields The structures of many protein molecules remain unsolved even after experts apply an extensive array of approaches. An international collaboration has led to a new, high-performance method that rapidly determined the structure of protein molecules in several cases where previous methods had failed. The usefulness of the new method is reported May 1 in Nature...

New method for unraveling molecular structures The team of Professor Burkhard Luy from KIT and Junior Professor Stefan F. Kirsch from the TUM has now shown for the first time that certain NMR parameters, the so-called residual dipolar couplings (RDCs), can make a significant contribution towards determining the constitution of chemical compounds when traditional methods fail. To do this they embedded molecules of the compound in a gel which slightly constricts their mobility. By stretching...

Ever since audiences heard Goldfinger utter the famous line, "No, Mr. Bond; I expect you to die," as a laser beam inched its way toward James Bond and threatened to cut him in half, lasers have been thought of as white-hot beams of intensely focused energy capable of burning through anything in their path. Now a team of Yale physicists has used lasers for a completely different purpose, employing them to cool molecules down to temperatures near what's known as absolute zero, about -460...
