 Title    Inequivalent Reorientation of the Trichloromethyl Groups in l,4-Bis(TrichloromethyI) Benzene as Studied by Pulsed 35C1NQR  
 Abstract    The temperature dependence of Ti of 35C1 N Q R o f the title com pound evidenced that the three crystallographically inequivalent CC13 groups have different potential barriers against reorientation (about 30, 36, and 42 kJ/mol). An intramolecular interaction between rc-electrons on the benzene ring and the C -C l bond is proposed to interpret the characteristic frequency splitting com m on to the 35C1 N Q R spectrum of each of the three inequivalent CC1? groups. The magnitude of T2 of each Cl atom is interpreted by intra-and intermolecular H • • • Cl interactions. It was found that only part of the temperature dependence of the N Q R frequency can be interpreted by reorientation.
