七、分子离子的裂解如上所述,由于轰击分子所用的电子能量大大超过从分子上轰走一个电子的能量,因此在一张质谱图上,除了分子离子峰外,其余绝大部分为碎片离子峰,其相对强度与分子的结构有极密切的关系。在质谱上,如果有几个主要 Separation of Molecular Ions As mentioned above, since the energy of the electrons used to bombard a molecule far exceeds the energy of an electron from the molecule, most of the rest of the spectrum on a mass spectrum is fragment ion Peak, the relative intensity of the molecular structure has a very close relationship. In mass spectrometry, if there are several major
