Inner beauty : The titanosilicate molecular sieve ETS‐10 has TiO 3 2− quantum wires (QWs) of varying length and local density along the [110] and [1 $\bar 1$ 0] directions (see picture). Analysis of the distribution of the QWs within a crystal using laser‐scanning confocal polarized micro‐Raman spectroscopy shows that they are not distributed evenly but in a symmetrical manner in an interesting pattern.
