✦ Synopsis

Tr.msien: and photochemical hole-burning is used to determine the homqeneous linewidths of the S, + So and Su t So . transitions of a magwsium porphin-pyridine comptex in four sites of n-octane (T= 1.1-4.2 I;). Thermally induced dephas-' ins of S, .-So is consistent 1% ith "exchange" to low-frequency local modes identified in the spectra. The relaxation time of SJ varies from ~2 to 4 ps from site to site.
