Abstract
Time-resolved triplet absorption and emission spectra of the title com pound were obtained using the diffuse reflectance laser flash photolys is (DRLFP) technique. The decays were non-exponential, indicating a no n-homogeneous distribution of adsorption sites and different conformat ional restrictions. Dispersive kinetics enabled us to obtain an averag e rate constant for the decay of (k) over bar = (6.9 +/- 1.3) x 10(5) s(-1) and a width of distribution of gamma = 3.4.
