✦ Synopsis

Results of picosecond photon-echo experiments on zincporphin in an ethanol glass at I .5 K are reported and discussed. At I .5 K, the two-pulse photon echo yields a pure dephasing time constant, a factor of 5.7 larger than the long-lived stimulated photon echo for a waiting time of 25 ms. This result accords with the prediction of the Bai-Fayer theory. However, the decay of the accumulated photon echo is much longer than expected.

Optical absorption and picosecond photon echo evpenments are used to study the dephasing of pentacene in benzoic acid. It IS shown that, while the absorption spectrum of pentacene is effected by proton transfer in the benzoic acid dimer, the dephasng IS caused by elastic and loelastx phonon scatter&

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-ech
