摘要：

The observed dipolar couplings of 4-chloroethoxybenzene in a nematic solvent are used to study the internal rotations about the O-C(H-2) bond. Accurate theoretical reproductions of these couplings are obtained using the standard three state (trans, gauche +/-) rotational isomer model with gauche rotation angle-phi(g) = 96-degrees and the trans-gauche energy difference E(tg) = 5.52 kJ mol-1. The probabilities and ordering matrix components of the trans and gauche forms are calculated.
