Caption

With previous methods, researchers could watch the nitrogen atom in a pyridine molecule bend up and down when excited by light. With this new method, they were also able to see changes in electron density happening at the same time. Blue bubbles depict decreasing electron density while red show increasing relative to unexcited pyridine.
