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、...

exact mass还是molecular weight 是根据质谱的分辨率来定了，现在新型质谱大多是高分辨率质谱，有的能精确到小数点后四位，所以一般都是exact mass。molecular weight是对分子量的计算一般不准确xact mass一般是含量丰度最高的同位素为基准计算出来的数值，如碳12，氢1等。而不考虑碳13和氢2,3等。molecular...
