超瑞利或二次谐波瑞利散射（HRS或SHLS）已被用于测量溶液中分子的平衡物理性质。本实验室已用它测定了取代苯甲酸和肉桂酸等弱有机酸在溶液中的离解常数。我们已经用HRS技术测定了分配系数、超分子结构的形成和化学计量、临界胶束浓度以及一个分子与另一个分子的结合或缔合常数。我们发现，分子的对称性及其在介质中的浓度在寻找新的化学应用的技术中发挥了重要作用。
Hyper-Rayleigh or second harmonic Rayleigh scattering (HRS or SHLS) has been employed to measure equilibrium physical properties of molecules in solution. It has been utilized in our laboratory to obtain the dissociation constants of weak organic acids such as substituted benzoic and cinnamic acids in solution. Partition coefficient, supramolecular structure formation and stoichiometry, critical micelle concentration, and binding or association constant of a molecule with another molecule have all been measured by the HRS technique by us. We find that both the symmetry of the molecule and its concentration in the medium play an important role in finding new chemical applications of the technique.
