In CCl.,/Ar and Ccl&r discharges the upper state (A 'A) of the 278 nm CC1 emission is populated by excitation of groundstate CCl(X TI) only at low CC& molar fractions. With increasing CCL content dissociative excitation of Ccl, into CCl(A 'A) dominates, while ground-state CC1 becomes increasingly co
The coupling of TiO 2 and transition metal complexes is attempted with the aim of higher functionalization of the TiO 2 photocatalyst. UV irradiation (λ ex > 300 nm) of a TiO 2 suspension containing equimolar aqueous solutions of FeCl 3 and K 3 [Fe(CN) 6 ] forms uniform thin films of "water-insolubl
