✦ Synopsis

Phosphorescence lifctim.?s for the ?I-alkyl benzenes are independent of the alkyl chain length for a gibe-en rigid glass at both liquid nitrogen and argon temperatures.

AppxenUy, the lifetimes decrease only if branching occurs nt the alkyt arbor. attached to benzene. Various alkyl substituents seem to affect bcnzcne little differently than changing the solvents. The need for lower temperature studies is emphasized; some of these are specified.
