通过使用与Goldschmidt类似的技术，已经编制了一组经验的“有效”离子半径。实际的半径值是由：(1)1000个实验原子间距离和(2)60多个同型氧化物和氟化物系列的离子体积与单位晶胞体积之间的近似线性关系得到的。这些半径考虑了电子自旋态以及阳离子和阴离子的配位，并已被发现与大多数氧化物和氟化物中的实验原子间距非常接近。阴离子半径绝对值的选择和与加性的某些偏差是很重要的，必须加以考虑。
An empirical set of'effective'ionic radii has been compiled by the use of techniques similar to those of Goldschmidt. The actual radius values were derived from:(1) 1000 experimental interatomic distances and (2) an approximately linear relationship between ionic volume and unit cell volume of over 60 isotypic series of oxides and fluorides. These radii take into account electronic spin state and the coordination of both cations and anions and have been found to reproduce closely the experimental interatomic distances in most oxides and fluorides. The choice of absolute values for anion radii and certain deviations from additivity are important and must be taken into consideration.
