The optical dephasing of pentacene in an o-terphenyl glass at 1.5 K is examined with picosecond photon echo and fluorescence line narrowing experiments. The homogeneous 7', is found to be l-3 ps, in contrast to all previous measurements on glass-chromophore systems in which the homogeneous 7'\* are
