When one thinks about chemistry, one doesn't usually consider quantum mechanics to play a part. Yet it does. When it boils down to it, all matter is a combination of a handful of subatomic particles and the forces holding them together. Chemistry, is in essence, applied physics. For decades, scientists have been trying to determine how to follow a chemical reaction from its initial state through all of its quantum states to its products. The hope was that, by doing so, researchers could understand the quantum dynamics that drive these reactions. Until now, it has mostly been speculation. However, a recent paper published in Nature by Liu et al. suggests that this may be possible.
