    • The viscosities of cyclohexane and CCU amount to 0.975 and 0.969 mPa s at 20 °C, ref 31. Therefore we take the value Jtdiff = 2.72 x 10'° M~' s~' derived in ref 14 for cyclohexane to. be also valid for CCU.

    • The sensitizers are listed in increasing triplet energy: teraphenylporphine, 9-bromoanthracene, phenalenone, phenazine, acridine, benzanthrone, 9-fIuorenone, duroquinone, 2-acetonaphthone, 4-benzoylbiphenyl, triphenylene, benzophenone, acetophenone.

    • The rate constants &r'A of the only mr* triplet sensitizers bepzophenone and acetophenone are not shown in Figure 1. These two values are by about 1 order of magnitude larger than expected by the correlation log(k-f/m) =f(&E), indicating that the electronic configuration of TI (πτ or rui*) could strongly affect the rate of O:('Ag) formation; see refs 19 and 41.
