关于原子折射度的问题早有人进行过研究。有实际意义的是有Eisenlohr、Vogel等人的工作。Eisenlohr和Vogel所建立的原子折射度系统均是从实测有机化合物的克分子折射度总结出来的,比较精确可靠。其缺点是仅包括不到十种非金属元素的原子折射度。 The problem of atomic refraction has long been studied. Practical work is done by Eisenlohr, Vogel and others. The atomic refractive systems established by Eisenlohr and Vogel are summarized from the molecular refractive indices of the measured organic compounds and are more accurate and reliable. The disadvantage is that it only includes the atomic refraction of less than ten non-metallic elements.
