"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 nuclear magnetic resonance (NMR) imaging.
"The technique can capture the structure of molecules at room temperature or very low or high temperatures and in many kinds of samples, including crystals, powders, gels, liquids and gases. It will be useful to scientists who study catalysis, energy storage, organic solar cells and biomembranes, among many other possibilities, Zheng said."
