Spectral holes have been measured for chlorin dopant educt and photoproduct states in six disordered systems : in glasses of o-terphenyl, benzophenone, polystyrene, ethanol, and triethylamine and on the surface of Al2O3 powder at 5 K. In contrast to the conventional picture of zero-phonon holes and phonon sideholes observable in the educt state, no zero-phonon hole is observable in the photoproduct state in glasses yet the absorption spectra exhibit a peculiarity resonant with the burning frequency ("Lambda-spectra"). A more complicated superpositional picture has been observed for Al2O3 powder The low-temperature hole spectra of an impurity in a 1D elastic lattice have been calculated and demonstrated to match qualitatively well the experimental observations. Physical relevance of such a model is discussed.
