摘要：

The phase transition of 2-bromoadamantane has been studied by means of H-1-NMR and X-ray diffraction. X-ray experiment shows that system is face-centered cubic with four molecule in a unit cell in the high temperature phase. Spin-lattice relaxation time T-1, Line width and second moment show a discontinuous change at 278 K on heating. Activation energies obtained from temperature dependence of T-1 are 13.1(5) and 13.7(3) kJ/mole in the high and low temperature phases, respectively.
