Crystal formation is a highly debated problem . By employing THz waves, it is shown that the crystallization of L‐(+)‐tartaric acid from water follows a non‐classical path involving intermediate hydrated states. The frontispiece image illustrates this crystallization process. The balloons on the top show structural schemes of the molecular arrangement in the different stages. The center of the figure represents a small section of the probed volume at a fixed time. The probed volume contains a mixture of the different stages. As time proceeds, the relative contributions of these phases to the total volume change. For more information see the Communication by H. Cölfen et al. on page 14128 ff.
