给出了分子与金属或电介质纳米线之间的货车范德华相互作用的诱导和色散偶极贡献的一般表达式。金属的非局部响应由一个标准的流体动力学介电函数，它提供了精确的和解析的反射因子的表达式。本文对HF分子与铝丝的平均距离进行了数值计算。然后考虑了非极性分子$（{\mathrm{N}}_{2}）$以避免任何化学吸附效应。分散性范德华力的各向异性导致了通过金属丝附近的分子的旋转跃迁，从而引起旋转排列。货车。
General expressions for inductive and dispersive dipolar contributions to the van der Waals interaction between a molecule and a metallic or dielectric nanowire are given. The nonlocal response of the metal is modeled by a standard hydrodynamic dielectric function, which provides exact and analytical expressions for the reflection factors. Numerical calculations are carried out for a HF molecule located at a mean distance from an aluminum wire. A nonpolar molecule $({\mathrm{N}}_{2})$ is then considered in order to avoid any chemisorption effect. The anisotropy of the dispersive van der Waals potential is responsible for rotational transitions of molecules passing in the vicinity of the wire, giving rise to a rotational alignment.
