Notes:
Nonphotochemical hole burning in glassy host/guest matrices generates a change of the site energy distribution of the guest molecules. This distribution of shifted energies has been determined by deconvoluting the difference of white-light excited fluorescence spectra before and after hole burning. For this aim, a special numeric algorithm has been developed. For the host/guest-system tetracene in ethanol, the observed shifts are within the inhomogeneously broadened line, but a shift to higher energies is predominant and amounts to about 20 wave numbers.
