✦ Synopsis


The homogeneous hnewidth (I',,~~) of the O-O St + So transitIon of free-base porphin (HzP) m polyethylene and Iglycerol has been studled via photochemical hole-bummg down to 0.3 K On lowermg the temperature the rhom a T1-3 relatton previously observed goes over to a linear dependence at the point where rhom = 60 hlHz At = 0 3 ii rhom III HzP m polyethylene reaches the hfetime-Iunited value of = 10 MHz Two recently proposed models that attempt IO e_~plam these results are dwzussed.

Spectral holes have been burnt in the S, Go O-O transition of resorufin in polymethylmethacrylate (PMMA) and glycerol, and of free-base porphin (H,P) in PMMA and polyethylene (PE). The holewidths follow a T 'J dependence over almost two orders of magnitude in temperature and extrapolate to the fluor
