Conference paper


The diffusion coefficient D of triplet anthracene in n-hexadecane (20 – 90 C) and n-hexane (25 C) was measured with the modified Avakian-Merrifield method. For n-hexadecane large deviations from the Stokes-Einstein equation are found. With the experimental values of D the rate constants for diffusion-limited triplet-triplet annihilation are calculated for both solvents and compared with experimental values. In n-hexane triplet-triplet annihilation is slower than diffusion controlled.
