✦ Synopsis

Photochemical hole-burning has been used to determine the temperature dependence of the homogeneous linewidth l-horn of the o-o s1 -SO tnnsition of free-base porphin (HzP) in 2-methyltetrallydrofur~n (BlTHF) from T = 5 K down to 0.4 K. A T1-30'o"5 dependence for rhom is observed which estrapolntcs to the lifetime-limited value (a10 MHz) at T = 0.05 K.

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
