【摘要】 本文研究结果表明,以ⅠA和ⅦA族元素组成的无机盐能用场解吸质谱(FDMS)进行分析。谱图是由一系列以[(AB)_nA]~+(A—ⅠA族元素,B—ⅦA族元素,n≥O)为通式的离子簇组成。离子簇n的大小随构成它的阴阳离子半径减小而增大。元素电离能呈周期性变化的规律能解释这类无机盐的FDMS行为和预测其它族元素组成的无机盐行为。根据对已知的无机盐的研究,本文还介绍了未知无机混合物和未知有机、无机混合物的FDMS分析,并确定了它们的结构。更多还原

【Abstract】 The types of ion occurring in the field desorption mass spectra of Ⅰ A and Ⅶ A elements and inorganic salts are discussed. Spectra consist of a series of cluster ions [(AB)_nA]~+ (A-cation, Banion, n>0). The cluster ions is increasing with the radius of amions and cations decreasing. The periodical rule of element ionization energy can explain the FDMS characteristic of the kind of salts and predict FDMS characteristic of other group inorganic salts. According to analysis of known inorganic salt, the FDMS analysis of mixture of unknown inorganic and the mixture of inorganic and organic are introduced, as well as their unknow components are also confired.更多还原
