Conclusions

  1. 1.

    The basic pathways of photochemical destruction of an electronically excited triphenylverdazyl radical (TPV) are stripping of hydrogen from the solvent with the formation of the corresponding leuco-base, as well as its dissociation at the N-N bond with the formation, in particular, of aniline and 1,3-diphenyl-1,2,4-triazole.

     
  2. 2.

    From the concentration dependence of the rate of quenching of the radical it was found that the product of the rate constant of concentration quenching (kq) by the lifetime of the excited state (Τ) is equal to 5·103 liters/mole.

     
  3. 3.

    The dipole moment of the radical (2.94 D in the ground state) increases to 9 ± l D upon excitation.
