1.1 Definitions
Photochromism is a photo-induced, reversible transformation between two isomers A and B of a chemical species with different absorption spectra. As a result, photochromic materials are generally characterized by a change in color during phototransformation between A and B.
In the remainder of this document, the reaction that leads from isomer A to isomer B will be denoted A → B and called the forward reaction. The...
