Title: TRIPLET ENERGY TRANSFER IN MIXED CRYSTALS OF BENZENE
Creators: Colson, S. D.; Tudron, Frank B.
Issue Date: 1974
Abstract: The dependence of intensity ratios for peaks corresponding to orientationally distinct molecules in mixed crystals of isotopic benzenes is determined. A significant deviation from the statistical limit is observed as the trap concentration varies over the range 0 to 1\%. Three systems are studied; $C_{6}H_{5} D$ in $C_{6}D_{6}$, $_{P}$-$C_{6}H_{4}D_{2}$ in $C_{6}D_{6}$, and $C_{6}H_{5} D$ in sym-$C_{6}H_{4}D_{2}$. The infinite dilution limit does not necessarily equal the statistical limit for occurence of the two traps. The variation in the intensity ratio with concentration can be explained in terms of energy transfer. The variation of the infinite-dilution intensity ratio from system to system is expected in light of an observed orientational effect on the lifetime.
