Cl3CCCH32Cl 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, T1 and T1 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 T1 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 T1 was carried out. The TCMP data are discussed and compared with those of hexamethylethane and hexamethyldisilane. Modified author abstract
