The homogeneous optical dephasing times (T,) and the non-photochemical hole burning (NPHB) linewidths of resorutin in glycerol glass are reported from 1.1 to 25.5 K. At low temperature, the linewidths obtained from NPHB are substantially wider than the linewidths (l/x T2) obtained from photon echo m
