| dc.description | This paper reports the results of a study that used systematic changes in the solvent viscosity to probe the photochemical reactivity of the Cpâ ²2Mo2(CO)6 (Cpâ ² = η<sup>5</sup>-C5H4CH3) molecule. The quantum yields for photolysis of Cpâ ²2Mo2(CO)6 in the presence of CCl4 were studied as a function of solvent viscosity. The quantum yields did not decrease to zero with increasing solvent viscosity but rather leveled off at a constant, non-zero value. This result cannot be explained by any of the previously reported radical or Moâ CO dissociation photochemical pathways for this molecule, and therefore an additional photochemical pathway is suggested to be operating in the reaction. The new pathway may involve a reactive isomer of Cpâ ²2Mo2(CO)6 or possibly electron transfer between the excited state of Cpâ ²2Mo2(CO)6 and CCl4. |
