ChemInform Abstract: Tentative Mechanism for the Bistability Observed During Irradiation of the Triphenylimidazolyl Radical Dimer in a CSTR.
Abstract
The mechanism of the photochemistry of the radical dimer (I) (already reported briefly in 1988) is studied in more detail in a continuous-flow stirred tank reactor (CSTR) and key reactions are summarized in a 6-step mechanism (four of them are given in the scheme).
ChemInform Abstract
The mechanism of the photochemistry of the radical dimer (I) (already reported briefly in 1988) is studied in more detail in a continuous-flow stirred tank reactor (CSTR) and key reactions are summarized in a 6-step mechanism (four of them are given in the scheme). The instability of the (I)/CHCl3 system observed is interpreted in terms of a photometric feedback mechanism. One of the key elements of this feedback mechanism is the screen effect of strong light absorbers on weaker ones.
