摘要：

H-1 nuclear magnetic resonance (NMR) spectra and birefringence of noncubic plastic single crystals (CH3)2 CCl2-CCl4 have been measured. The investigation has demonstrated that in these crystals weak preferred orientations of molecules were observed. Concentration dependence of orientational ordering matrix of (CH3)2 CCl2 molecules has been obtained from computer simulations of NMR line shape and birefringence data. It has been found that all ordering matrix elements become zero at mole fraction of 2,2-dichloropropane 0.5.
