在分子二聚体中测量了作为温度的函数的强电极化率，该分子二聚体被一对氢键弱结合。这个系统是一个显著的例子，其中磁化率中的主要项是由振动诱导的电偶极子引起的。结果表明，偶极矩的平均平方与温度成线性关系，磁化率不符合通常的1/T居里定律。这一壮观的效应表明了动力学对解释弱结合络合物性质的重要性。
A strong electric susceptibility is measured as a function of temperature in a molecular dimer which is weakly bound by a pair of hydrogen bonds. This system is a remarkable example where the dominant term in the susceptibility is due to a vibration induced electric dipole. As a consequence, the averaged square of the dipole moment varies linearly with the temperature and the susceptibility does not follow the usual 1/T Curie law. this spectacular effect demonstrates the importance of dynamics to interpret the properties of weakly bound complexes.
