The temperature dependence of the width of spectral holes in the crystalline and glassy phase of bcnzophenone:chlorin solid solutions is measured between 1.5 and 10 K. In the crystal, the holewidth levels on r(O) ~45 MHz for T-C 5 K. This is close to the lifetime-limited value. For T> 5 K, it exhibi
