【摘要】 本文研究了中性醋酸钴～十四酸钴盐的EIMS谱及其特殊质谱行为,首次测定了醋酸钴～异戍酸钴的i-C₄H₁₀-CIMS和NCIMS谱,发现该系列化合物的EIMS和CIMS谱相似,NCIMS谱在分子离子两侧有±14n系列峰,目前尚无法给予合理的解释。更多还原

【Abstract】 Neutral cobalt carboxylates are converted into their basic forms in the ion source during vaporization. The three most abundant peaks in EI spectrum of every salt are [Co₄O（OCOR）₅]^+· , [Co₄O（OCOR）₅]+ and [Co₂O（OCOR）₃]⁺. The protonated molecular ion in i-C₄H₁₀-CIMS is the base peak. NI spectra of cobalt carboxylates are unique in that they are dominated by the base peak of the molecular ion [Co₄O（OCOR）₆]^- and ± 14n amu peaks on either side of it. The explanation for the formation of ions through gaining and losing multiples of CH₂ units is not yet clear and further investigation is required.更多还原
