The shape of the lowest exciton absorption band in rx- and /j-perylene due tothe B..eA. transition, the halfwidth of the absorption band, and the steepnessparameter of the Urbach tail are investigated. From.]inear temperature depend-ence of the halfwidth and the Lorentzian line-shape, the transition A.<-A. is wellexplained by the exciton band picture. The lattice relaxation behavior of excitonsafter thev are formed is described b>' the stronx exciton-rhonort courlinz scheme.Based on the steepness parameter obtained, 0.93 in<z-perylene and 1.38 in/7-perylene, and the amount of the Davydov splitting obtained, 2040 cm ' ina-perylene and 960 cm ' in /7-perylene, the lattice relaxation energy is estimatedto be 1530 cm ' and 523 cm ' respectively. Also tlte energy difference betweenthe free and self-trapped exciton states is expected to be 620 cm " in a-peryleneand 43 cm ' in /7-perylene.
