Raman microscopy has been used to study the crystal‐to‐crystal photodimerization of 9‐methyl‐anthracene, analyzing the time evolution of both the molecular and the lattice phonon spectra during the transformation from the reactant to the product. This has made possible the concomitant detection of the chemical and crystal lattice changes in the same portion of the irradiated crystal. The topochemical mechanism of this reaction produces a fast process leading to a complete transformation of the monomer into the dimer. Copyright © 2016 John Wiley & Sons, Ltd.
