WebJan 1, 2015 · Photochromism is simply defined as a light-induced reversible transformation of a chemical species between two forms that have different absorption spectra. … Photochromism is the reversible transformation of a chemical species (photoswitch) between two forms by the absorption of electromagnetic radiation (photoisomerization), where the two forms have different absorption spectra. In plain language, this can be described as a reversible change of color upon exposure to light.
