摘要: The good understanding of a photochromic reaction mechanism requires the establishment list all transient species and definition their connecting processes. purpose kinetic studies is determination main parameters, such as quantum yields photoisomerization, rate constants thermal relaxation spectra species. These data allow structure properties relationships in order to select best substituents improve performances within given series. In this review, we describe dynamic behaviour various systems during after irradiation, from simplest mono-exponential decay more complicated multi-exponential dynamics. Then, analyse evolution long-lived isomers under continuous irradiation. Several pedagogical examples tricks perform easy analysis are appendices.
