摘要：

The molecular dynamic of tert-butyl chloride confined to pores of 24.4 Angstrom of MCM-41 is investigated by deuterium NMR spectroscopy. The temperatures of the all phase transitions are depressed by about 10 K in porous MCM-41 relative to the bulk transitions. The rotation of the (CD3)(3) about C-CI (C) axis is less restricted than CD3 rotation about C-C bond (C-3) axis. Variable temperature lineshape analysis yield the activation energy for C3 rotation of E-a = 5.2 kcal/mol in good agreement with E-a = 4.5 kcal/mol obtained from the temperature dependence of spin-lattice relaxation times.
