The current IUPAC-recommended definition of the term "nominal mass," based on the most abundant naturally occurring stable isotope of an element, is flawed. We propose that Nominal mass should be defined as the sum of integer masses of protons and neutrons in any chemical species. In this way, all isotopes and isotopologues can be assigned a definitive identifier. Graphical Abstract ᅟ.
当前基于元素最丰富的天然稳定同位素的 IUPAC 推荐术语“名义质量”定义存在缺陷。我们建议将“名义质量”定义为任何化学物质中质子数和中子数之和的整数质量。通过这种方式，可以为所有同位素和同量异位素分配一个明确的标识符。图摘要 ᅟ。
