✦ Synopsis
Spectral holes have been burnt in the S r +-Se O-O transition of resorufin in two phases of ethanol glass between 0.3 and 4.2 K. The holewidths differ by a factor of 8 and follow a T '.3 dependence. The homogeneous linewidths (r,,,) in one of the phases are about half those derived from a photon-echo experiment by Payer and co-workers. Holes burnt between -600 and 573 nm yield the same holewidth. It is concluded that hole-burning measures rho,,, in this amorphous system.

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
