The effect of different additives on the one-color and two-color hole
burning in the S-1 bands of zinc tetrabenzoporphine and 1,2-benzanthra
cene has been investigated in solvent glasses at 7-9 K. Two different
mechanisms of activated hole burning have been observed: electron tran
sfer to the accepters and triplet energy transfer to the olefins follo
wed by cis-trans isomerization. The decomposition rate of 1-azidopyren
e was determined from the hole width to be as fast as 130 fs.
