✦ Synopsis

Investigation of the photochromic system TPID/CHC13 (TPID = triphenylimidazolyl dimer) in a CSTR provided the first example of isothermal photochemical bistability. The reaction mechanism was established and the relevant kinetic and spectroscopic parameters were estimated experimentally. In order to predict the quantitative dynamic behavior of the TPID/CHC13 system these parameters were refined numerically using batch reactor data.

The adjusted model simulates very accurately bistability either as a function of residence time T, or as a function of incident photon flux I@.
