内容記述(抄録等)
The Zeeman effect of the ^<35>Cl NQR of 2,6-Dichlorobenzyl chloride was observed. The three absorption lines were assigned to the three chlorine atoms, referring to the bond directions which were determined on the basis of the orientations of the principal z axes. The locations of the principal z axes of the field gradient were determined with uncertainty below 0.1°. The asymmetry parameters of the electric field gradients were found to be 0.120±0.002, 0.110±0.002, 0.008±0.002, respectively, for the three chlorine atoms corresponding to the resonance lines in order of decreasing frequency. The two higher-frequency lines were assigned to the chlorine atoms bonded to the ring and the lower-frequency line was assigned to the chlorine atom bonded to the side chain.
