Comments: The extinction coefficients and oscillator strengths were measured for the first strong triplet <--> triplet transition in naphthalene, phenanthrene, 
and triphenylene. The results are: naphthalene, epsilon(max) = 14000 liter/mole cm, f = 0.05; phenanthrene, epsilon(max) = 27000 liter/mole cm, f = 0.11; 
triphenylene, epsilon(max) = 7000 liter/mole cm, f = 0.05.
