✦ Synopsis
A study of eschange sir&t-singlet energy transfer was made between a series of stcrically hindered ketones end a-diketones in fluid cyclohesane.
The comparison of the measured rate constants of energy transfer shows them to be nearly diffusion controlled and insensitive to stcric hindrance. This is argued to be 3 solvent cage effect. That is, the rate of energy transfer in a bimolecular collision may be sensitive to stcric hindrance, but the many collisions within the cage result in a transfer efficiency of unity.
