Isotropic Intermolecular(各向同性分子间)研究综述
Isotropic Intermolecular 各向同性分子间 - Electric and magnetic field gradients, arising from sufficiently strong anisotropic intermolecular forces, tend to induce molecular polarization which can often modify substantially the results of molecular collisions, especially at low rotational temperatures and low collision energies. [1] We propose a new thermodynamic approach for nonspherical molecules by applying a perturbation theory in which an anisotropic intermolecular potential, the hard Gaussian overlap, is the reference system. [2] Using two-dimensional IR spectroscopy, we demonstrate the formation of contracted ion pair configurations in nitric acid solutions between NO3- ions and H+(aq) via the observation of a distinct anisotropic intermolecular crosspeak between these species. [3]由足够强的各向异性分子间力引起的电场和磁场梯度往往会引起分子极化，这通常可以大大改变分子碰撞的结果，尤其是在低旋转温度和低碰撞能量下。 [1] 我们通过应用微扰理论为非球形分子提出了一种新的热力学方法，其中各向异性分子间势，硬高斯重叠，是参考系统。 [2] 使用二维红外光谱，我们通过观察这些物种之间明显的各向异性分子间交叉峰，证明了硝酸溶液中 NO3- 离子和 H+(aq) 之间形成收缩的离子对构型。 [3]
