✦ Synopsis

Picosecond absorption spectroscopy has been used to examine the primary pho~oprodact of Cr(CO), in both neat and mixtures of THF and cyclohexane. The primary intermediate observed is shown to be she solvated pentacarbanyl in uhich one solvent molecule occupies the coordination sire created by the photoeL%mination of CO_ The rate of exchange of cyclohexane from (cyclohexane)Cr(CO)s by THF to form (THF)CI(CO)~ was found to be bimolecular, k = (4 t 1) X lo7 mole-' s-1 1 with an enthalpy and entropy of activation of 1 f 1 kc&mole and -20 5 4 eu. respectively_
