摘要：
On the basis of Mo-96 T1 measurements made on samples Of MO(CO)6 encapsulated in dried Na-Y zeolite over the temperature range 223-323 K, it is confirmed that Mo(CO)6 experiences significant rotational freedom in the 13-angstrom zeolite supercages. In addition, it is found that the activation energy for rotation is about 40 +/- 4 kJ mol-1, and the ambient temperature rotational correlation time, tau(c), is approximately 3 orders of magnitude longer than is tau(c) in solution.
