Exact Mass是准确分子量,一般精确到小数点四位 Exact Mass是准确分子量,如果有具体例子介绍一下就更好了:) HBr Exact Mass: 79.93 Mol. Wt:80.91m/e:79.93(100%),81.92(97.3%)
在chemdraw软件中,这一区分更为直观。exact mass被标示为单质量,为质谱分析提供精确的同位素质量数据,帮助研究人员确定化合物的精确组成。与此相反,molecular weight则代表了化学分子量,适用于广泛的化学分析,包括但不限于计算溶液浓度、分子比等。两者的应用范围各异。分子量在化学合成、反应机理研究、...
如果你说的是chemdraw里的话,exact mass是monoisotopic mass,molecular weight是化学分子量,前者给质谱...
