NMR Static and Rotating Frame Relaxation Studies in Solid Cl3CC(CH3)2Cl.
Abstract
Cl3CC(CH3)2Cl (1,1,1,2-tetrachloro-2-methylpropane or, briefly, TCMP) was investigated by means of temperature dependent static and rotating frame spin-lattice relaxation times, T(1) and T(1 rho), respectively, between 102K and 423K. Overall molecular tumbling as well as self-diffusion were determined from the data in the high temperature cubic phase. Proton-chlorine dipolar relaxation contributions were observable because of short chlorine spin-spin and spin-lattice relaxation times. An estimate of the chlorine T(1) values and correlation times in the high temperature phase is given. The influence of impurities on the results is dealt with also, and an attempt to separate the impurities' contribution to T(1) was carried out. The TCMP data are discussed and compared with those of hexamethylethane and hexamethyldisilane. (Modified author abstract)
