非金属元素的分子间货车德瓦耳斯半径已被汇编成一个“推荐”值的列表，用于体积计算。这些值是通过从最可靠的X射线衍射数据中选择那些可以与0 K下的晶体密度相一致的值而得到的。(to给出合理的堆积密度）、气体动力学碰撞截面、临界密度和液态性质。通过与最外层价电子的布罗意波长的关联，对货车德瓦耳斯半径的性质提供了定性的理解，并提出了金属有机化合物中金属元素的货车德瓦耳斯半径的暂定值。本文最后列出了热碰撞不能穿透的分子体积的增量，即所谓的货车德瓦耳斯体积，以及相应的每个分子面积的增量。
Intermolecular van der Waals radii of the nonmetallic elements have been assembled into a list of “recommended” values for volume calculations. These values have been arrived at by selecting from the most reliable X-ray diffraction data those which could be reconciled with crystal density at 0 K.(to give reasonable packing density), gas kinetic collision cross section, critical density, and liquid state properties. A qualitative understandingof the nature of van der Waals radii is provided by correlation with the de Broglie wave length of the outermost valence electron. Tentative values for the van der Waals radii of metallic elements—in metal organic compounds—are proposed. The paper concludes with a list of increments for the volume of molecules impenetrable tothermal collision, theso-called van der Waals volume, and of the corresponding increments in area per molecule.
