Structural snapshots of complex molecules

US researchers have pioneered a new spectroscopy technique to uncover the precise sequence of atomic movements and structural changes that occur during complex chemical transformations.  

The scientists used the new method to pin down the changes that occur when green fluorescent protein (GFP) glows under blue light, and say the approach could be used to further understand important chemical transformations in other complex molecules, as well as tailor new molecules.  More...
